Truncate

Overview​

This function truncates a number to an integer by removing its decimal, or fractional part.

CHelper.Math.Truncate(Number)

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

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 input parameter is either too long or undefined.
  • Use the IsNaN function to validate the parameter is a number.

Example​

In a Purchase Request Process, an estimation of the price of a product is made based on the last three purchases of that product. The purchasing values are averaged to obtain the estimation. Likely this estimation will have a decimal part. In order to obtain an integer value, the Truncate function can be used:

Math20

//Obtain the estimated price by averaging the last three purchasing prices

EstimatedPrice = CHelper.Math.Average([<Product.Price1>,<Product.Price2>,<Product.Price3>]);

//Obtain the integer part of the estimated price

<Product.IntEstimatedPrice> = CHelper.Math.Truncate(EstimatedPrice);
