=='''General Description'''== {{JavaScript Syntax}}
==General Description==Executes an expression to calculate a value and store the result. Additional information can be found in the [[SmartSimple]] wiki. =='''Field Options'''==
* '''Allow Empty''': N/A* '''Default Text''': N/A* '''Options''': Expression* '''Track Changes''': Yes* '''Store To Value''': N/A =='''Special Options for Field'''== {{FieldOptions}}
* '''Expression''' – defines : Defines the expression to be executed.(additional details on Expression found in section below){{LabelAboveField}}{{ToolTip}}{{HideFieldForNewRecord}}{{SmartFieldView}}
==Expression Field Details=='''Expression''': Defines the expression to be executed All values are treated as strings. For arithmetic operations, PARSEINT and PARSEFLOAT functions are used to convert the string value to a numeric value.
Example summing the values using five custom fields:
''ParseFloatssParseNum([Total Monthly Cost]) + ParseFloatssParseNum([Total Cost Ex]) + ParseFloatssParseNum([Hardware Rental]) + ParseFloatssParseNum([Email]) + ParseFloatssParseNum([Other])'' =='''<pre>If you are using this field in a "Dynamic Control Field Validation'''== " address the fields by their field ids with the following syntax: frm.cf_customfieldid.value  Example: ssParseNum(frm.cf_1254625.value)*0.44</pre>

You can use arithmetic, string, comparison operators and functions within the calculated [[Custom Field|custom field]]. ==Value Storage==* References to other fields are always enclosed in square brackets: [variable1] * The calculations are performed when you click the '''Save''' button and save the page. {{ValueStoresTo}}
=='''Important Notes on Calculation Order'''==
* Calculated field formulas are executed in the same order that the calculated fields are displayed on the page. * You must not place fields that perform summary calculations based on other calculated fields ABOVE the subordinate calculations. * If the fields are ordered in this manner, saving the page will not update the summary calculation, as summary formula will be executed BEFORE the subordinate calculations are performed.{{CFPermissionsTab}}
 
 
==Notes==
* You can in general use either the name of the field within square brackets, or frm.cf_''customfieldid''.value to refer to the values for the calculations.
* In both cases is that the field must be visible on the page (or a [[Hidden Value]] custom field that is on the page).
* A [[Combo Box]] custom field can be used in mathematical as long as the stored value is numeric. The displayed value does not have to be numeric
* [[Check Boxes]] cannot normally be used in Calculated Value fields. (They can be accommodated with sufficient knowledge of JavaScript)

==SmartSimple Calculated Field Operators==
===Arithmetic Operators===
[[Image:CS08.png]]
===Arithmetic Operators==='''Rounding''': ** To round a calculation to 2 decimal places use the following syntax:*** '''Math.round(('''''expression''''')*100)/100''''''Note:''' To round to a different decimal place just change '''*100)/100''' part as per requirement. Example:To round to 3 decimal places, you would use '''Math.round(('''''expression''''')*1000)/1000'''
[[Image*** For no decimal places:CS08**** '''Math.pnground('''''expression''''')'''where ''expression'' is the calculation to be rounded off, such as PARSEINT([variable 1])/PARSEINT([variable 2])
===String Operators===
 
[[Image:CS081.png]]
===Comparison Operators===
 
[[Image:CS084.png]]
===Date Functions===
[[Image:CS085.png]]
 
'''calage([date of birth])''' - Calculates the number of full years between the current date and the date included in the function.
'''calage([date of birth],1)''' - Calculates the number of years and months between the current date and the date included in the function as a floating point.
'''calage([date of birth],2)''' - Calculates the number of years and months between the current date and the date included in the function as the string "X years and Y months".
 
===Time Functions===
To calculate the time difference for '''Standard Fields''' in hours and minutes use the following
 
Level 1:
[[Image**** ''timediff(frm.ostartdate.value,frm.oenddate.value,frm.ostarthour.value,frm.ostartminute.value,frm.oendhour.value,frm.oendminute.value)''Level 2:CS085 **** ''timediff(frm.startdate.value,frm.enddate.value,frm.starthour.value,frm.startminute.value,frm.endhour.value,frm.png]]endminute.value)''(note: the starttime and endtime '''Standard Fields''' are actually stored as part of the startdate and enddate fields, which is why they are used here)
===Other Functions===
To show the number of characters in a text field, use:
**** [[Image''fieldname''].lengthTo show the number of words in a text field, use:CS086.png]]
**** [''fieldname''].split(" ").length==See Also==**** [[How Calculated Custom Fields Work]]**** [[ssParseNum]]**** [[Template / Type Formula]]**** [[:Category:Custom FieldsJavaScript]]**** [[Variable List]]**** [[The Musings of Chin - Correct Variable Processor Use]]**** Disambiguation: [[Calculated Field|Calculated Field in Reporting]]{{CustomFieldPageFooter}}
