تابع Power / توان

Overview

This function obtains the result of a number raised to a power.

 

CHelper.Math.Pow(Base,Power)

 

The parameters of this function can be defined as Xpaths, variables or numbers.

 

Considerations

•Input parameters 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 an error if the Base is between 1 and -1 and the Power is either too long or negative number.

•The function returns an error if the Base is either too long and the Power is greater than zero.

•The function returns an error if the Base is negative and the Power is not integer.

•The function returns an error if the Base is not between 1 and -1 and Power is too long.

•The function returns an error if the Base is zero and the Power is negative.

•The function returns an error if the Base or Power are undefined.

•Use the IsNaN function to validate the parameters used are numbers.

 

Example

In a Credit Request Process a customer wishes to know what would be the total amount that he/she has to pay in a Personal loan after six months under a given interest rate.

This amount can be calculated using the following formula:

 

 

Where Po is the requested amount, i is the monthly interest rate and P is the amount at the month n.

 

To perform this calculation in Bizagi you can use the Power function. This function receives two parameters: Number and power.

As the requested amount and interest rate are known, the final amount can be easily calculated as follows:

 

 

//Obtain the parameters of the formula in variables

Po=<CreditRequest.RequestedAmount>

i=<CreditRequest.InterestRate>

//Apply the formula to obtain the final amount

<CreditRequest.FinalAmount>=Po*CHelper.Math.Pow(1+i,6)
