'''Important''': After manually editing the expression, You can create expressions (formulas) directly in the regular operators dashboard components. It can thus display calculated values that are not be used until you ''Clear All'' present in the filters;data source file/spreadsheet.

==== Value type operand ====Are numeric values of * If the float type (Real numbers domain). These values allow component has the use of an integer columns ''Total Price'' and a fraction part''Quantity'', separated by you can create an expression to calculate the dot (.) character (decimal separator)''Unit Price''. Would be like this: ** ''Total Price'Examples'/ '': 1Quantity''* In addition, 1.05you can use fixed values, 2.55;such as:** ''Total price'' / 10

==== Date type operand ====Are values We just remember that express any datecurrently TaticView only supports expressions whose numeric return. It is possible to determine a date representing it as a string, being delimited by the simple quote (') character and separated by the bar (/) character. The default supported format is "dd/MM/yyyy". '''Examples''': '01/01/2011', '29/02/2000';

==== Identifier type operand ====Are values that represents a field or variable in Below are details about how the expression. Used to make reference to data source columns, delimited by double quotes ("). '''Examples'''expressions work: "City.City", "Product.Product";

==Basic structure of a Expression (Formula) == Parenthesis ====Used to group and separate expressions parts. Expressions inside parenthesis are processed first. '''Examples''': ("Profit" / "Total Price" ) + 10

It's the numerical values. You can use both while values and decimal values. For decimal values, the decimal separator should be the point. * Examples: 1, 1.05, 2.55  ==== Text Operand ==== It's the text operands. If you want to use this type of operand in a expression, you must delimit them by the single quotation mark ('). * Examples: 'John Snow', 'California', 'Spaghetti'  ==== Date Operand ==== These are values that express any date. To represent a date in expressions the behaviour is similar to text operands, i.e. the content must be surrounded by single quotation marks ('). However, the mask ''dd/MM/yyyy'' must be used. * Examples: '01/01/2019', '14/11/2019', '25/12/2019'  ==== Boolean Operand ==== They're operators of the true or false type. Normally user to validate, or not, a condition in a more complex expression. * Examples: true, false  ==== Parentheses ==== Used to group and separate parts of on expression. Expressions within parentheses are processed first. * Example: ("Profit"/"Total Price") + 10  ==== System variable Operand ==== These are predefined variables in the system. To use the system variables you must precede them by hashtag (#) and delimit them by double quotes("). Currently only the "#null" variable is available and indicates null content. * Example: IF("Product" == "#null";0;20)  == Arithmetic Expressions === Arithmetic expressions relate two operands (which can be any the operands described above, or another expression) to make up the sum, subtraction, multiplication or division.

Sum Add two value operandsor another expression result. Represented by the sum (''+) character'' charecter. Syntax: '' <operand/operating or expressionresult> '''+ ''' <operand/operating or expressionresult>''. Example: '''Examples''': "Taxes" + "Commissions";''' - Sums the values of the fields ''Taxes'' and ''Commissions'' 

 Subtract two value operandsor another expression result. Represented by the subtract or hyphen (''-) character'' charecter. Syntax: '' <operand/operating or expressionresult> '''- ''' <operand/operating or expressionresult>''. Example: '''Examples''': "Gross SalePrice" - "Taxes";''' - Subtracts the values ​​from the ''Price'' and ''Taxes'' fields. 

Multiplies two value operands or another expression result. Represented by the multiplication charecter ''*''. Syntax: <operating or expression result> '''*''' <operating or expression result> Example: '''"Quantity" * "Unit Price"''' - Multiplies the value of the ''Quantity'' field by the value of the ''Unit Price'' field.  ==== Division(/) ====Divides Divide two value operandsor another expression result. Represented by the divide or bar (division charecter ''/) character''. Syntax: '' <operand/operating or expressionresult> '''/ ''' <operand/operating or expressionresult>''. Example: '''Examples''': "Total ValuePrice" / "AmountQuantity"''' - Divides the value of the ''Price'' field by the value of the ''Quantity'' field.  == Relational Expressions == Relational expressions compare two operands (value/text or other expression) to assess whether a condition is true or false. Normally used with decision functions, such as ''IF''. 

It compares if two operands are the same, returning true if they are the same or false if they are different. Represented by the equality operator ''=== Relational Expressions ===''.

The relational expressions compare two operands (value Syntax: <operating or another expression) to evaluate if a condition is result> '''=='true'' <operating or expression result>Example: '''falseIF("Product" == "#null";0;20)''. Usually used with decision functions' - If the ''Product'' is null, like return the value ''IF0''.Otherwise return the value ''20''

Performs the different comparison expression between It compare if two operandsare different, returning true if they were different or false if equal. Represented by the different differente operator (''!=)''. Syntax: '' <operating or expressionresult> '''!= ''' <operating or expressionresult>''.Example: '''Examples''': IF("City.CityProduct" != 'New YorkLasagna';0;20)''' - If the ''Product'' is different from ''Lasagna'', return the value ''0''. Otherwise return the value ''20'' 

Compares if the first operator (from the left) is greater than the second operator (from the right), returning true if it is greater and false if it is lesser or equal. Represented by the greater operator ''>''. Syntax: <operating or expression result> '''>''' <operating or expression result>Example: '''IF("Gross Value" > 1000;1;0)''' - If the ''Gross Value'' is greater than ''1000'', returns the value ''1'', if not the value ''0''  ==== Greater or equal than to (>=) ====Return ''true'' Compares if the first expression operator (from the left) is greater than or equal to the second expression operator (from the right), returning true if it is greater or equal and ''false'' otherwiseif it is lesser. Represented by the greater or equal operator ''>=''. Syntax: <operating or expression result> '''>=''' <operating or expression result>Example: '''IF("Gross Value" >=2500;100;0)''' - If ''Gross Value'' is greater than or equal to ''2500'' returns ''100'', otherwise returns ''0''  ==== Less than (<) ==== Compares if teh first operator (from the left) is lesser than the second operator (from the right), returning true if it is lesser and false if it is greater or equal. Represented by the Lesser operator ''<''. Syntax: <operating or expression result> '''<'''<operating or expressionresult> Example: '''IF("Gross Value" < 100;50;200)''' - If ''Gross Value'' is less than ''100'', returns ''50'' if not ''200''  ==== Less or equal to (<=) ==== Compares if the first operator (from the left) is lesser or equal to the second operator (from the right), returning true if it is lesser or equal and false if it is greater. Represented by the lesser or equal operator ''<=''. Syntax: <operating or expression result>'''<= ''' <operating or expressionresult>Example: '''IF("Gross Value" <= 500;100;0)''' - If ''Gross Value'' is less than or equal to ''500'' returns ''100'', if not ''0''  == Logical Expressions == Logical expressions group together two operands (Boolean or other expression) to make up a logical expression, in order to evaluate the relationship of two Boolean operators to a true or false result. This type of expression is usually used for decision making, such as IF and with relational expressions.  ==== And Operator (&&) ==== Executes the logical operation ''AND'' between two Boolean values. Both values must return true so that the result of the operation is true. Represented by the ''&&''operator. Syntax: <expression> && <expression>Examples: ''': IF(("Order DatePrice" >0) && ("Seller" == '01/01/2011John Snow');450;0)''' - If ''Price'' is greater than ''0'' '''AND''' ''Seller'' is equal to ''John Snow'', returns ''450'' if not returns ''0'' '''IF(("Order DateCity"!= "#null") && ("Product" != 'Lasagna');1;0);''' - If ''City'' is non-null '''AND''' ''Product'' is different from ''Lasagna'' returns ''1'' if it does not return ''0'' 

==== Lesser than Or Operator (<||) ====Return ''true'' if the first expression is lesser than the second expression and ''false'' otherwise. Represented by the lesser operator (<). Syntax: ''<expression> < <expression>''. '''Examples''': "Profit" < '0';

==== Lesser or equal than (<=) ====Return Performs the logical ''trueOR'' if operation between two Boolean values. A two values must be true so that the first expression result of the operation is lesser than or equal to the second expression and ''false'' otherwisetrue. Represented by the lesser or equal operator (<=). Syntax: ''<expression> <= <expression>''. '''Examples''': IF("Order Date" <= ||'01/01/2011';"Order Date";0).

'''IF(("City" !="#null") || ("Product" !== Logical Expressions ==='Lasagna');1;0)''' - If ''City'' is non-null '''OR''' ''Product'' is different from ''Lasagna'' returns ''1'' if it does not return ''0''

==== And Denial Operator (&&!) ====Performs the logical operation ''AND'' between two boolean values. The two operands must be ''true'' for the result of the operation to be ''true''. Represented by the ''AND'' operator (&&). Syntax: ''<expression> && <expression>''. '''Examples''': IF((Gross Sales > '0') && (Seller == 'John Snow');'Sold';'Not Sold'), IF((City!="#null") && (Date<DAY_FROM_TODAY(0));1;0);

==== Or (||) ====Performs the logical negation operation ''OR'' between two for a boolean valuesvalue. One of the two operands must be ''true'' for If the result of the operation is true the negation operator converts to be ''true''false and vice versa. Represented by the ''OR'' operator (||). Syntax: ''<expression> || <expression>!''. '''Examples''': IF((Gross Sales > '0') || (Sold == 'true');'Sold';'Not Sold'), IF((City!="#null") || (Date<DAY_FROM_TODAY(0));1;0);

==== Not (Syntax: !) ====<expression>Example:Performs the denial logical operation for a boolean value. If the operand are ''true'IF(!BETWEEN("Delivery Date"; ' the 01/01/2015'; 'NOT31/12/2015');2016;2015)' convert it to ''false'' (and the other way around). Represented by - If the ''NOT'' operator (!). Syntax: Delivery Date''! <expression>is ''. 'NOT''Examples'between '': IF(!BETWEEN("Date", '01/01/20132015'' and ', '12/31/12/20132015'');returns 'Not 2013';2016'2013').If between this period returns ''2015''
