تابع Absolute Value / قدر مطلق

Overview

This function returns the absolute value of a number.

 

CHelper.Math.Abs(Number)

 

The parameter of this function can be defined as an XPath, variable or a number.

 

Considerations

•The input parameter must be double.

•The supported attribute types to use as input XPath parameter (or Xpaths stored in variables) are: integer, currency, float, real.

•The function returns error if evaluates an undefined parameter.

•Use the IsNaN function to validate the parameter used is a number.

 

Example

In an Expenses report Process an employee registers all the expenses of a business trip. If the expenses are higher than the approved ones, the difference has to be discounted from payroll. As this difference is always negative but the amount to discount has to be positive it is necessary to use the Abs function:

 

 

//Evaluate if the registered expenses are greater than the approved ones

if (<ExpensesReport.TotalExpenses> > <ExpensesReport.ApprovedExpenses>)

{

//If so obtain the absolute value of the difference

<ExpensesReport.AmountToDiscount> = CHelper.Math.Abs(<ExpensesReport.TotalExpenses> - <ExpensesReport.ApprovedExpenses>)

}else{

//If not assign 0 to the amount to discount from payroll

<ExpensesReport.AmountToDiscount>=0

}
