# Compatibility Functions

- 3 minutes to read

Compatibility functions were replaced with new functions in Microsoft® Excel® 2010 and higher. However, they are still available for backward compatibility with earlier Excel versions. Our WPF Spreadsheet control correctly interprets and evaluates these functions.

We recommend that you use new and more precise functions instead of the functions listed below.
