# Compatibility functions (reference)

Click one of the links in the following list to see detailed help about the function.

Important    All of these functions have been replaced with new functions that may provide improved accuracy and whose names better reflect their usage. These functions are still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider using the new functions from now on, because they more accurately describe their functionality.
