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. The Purchase department has decided to round this estimation down to obtain an integer estimation. For this case the Floor function can be used:




//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.Floor(EstimatedPrice);
