•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.

In a Credit request process the information of interest rates is entered and displayed in Forms as numbers between 0 and 100. Suppose in an activity of the Process the interest amount caused in one period must be calculated. The process cannot use this number to perform the calculation so it must be normalized into a number between 0 and 1 to obtain a coherent and accuracy result. To do that in Bizagi you can use the Percentage function:
//Obtain the Interest rate (Between 0 and 1)
RealInterestRate = CHelper.Math.Percentage(<CreditRequest.InterestRate>);
//Calculate the Interest amount
<CreditRequest.InterestAmount> = RealInterestRate * <CreditRequest.RequestedAmount>;
