#GPPT Using .Net Math Functions from Microsoft Dynamics GP

David Meego - Click for blog homepageA recent customization project I was working on using GP Power Tools required the calculation of a square root as part of some number crunching needed to work out material quantities on a Sales Order Processing transaction.

While Dexterity (the language behind Microsoft Dynamics GP) is great at accounting style mathematics (as per a standard calculator), it does not have advanced functions for powers, logs, and trigonometry (as per a scientific calculator). This means that there is no “native” method to calculate a square root.

However, Dexterity (from v14.0 onwards) has a .Net Interop which allows you to import and call .Net libraries directly from your Dexterity scripts. This example shows how to call the System.Math library as well as other advanced techniques, such as Custom Forms and Virtual Fields.
