# Math and Trigonometric Functions (DAX)

The mathematical functions in Data Analysis Expressions (DAX) are very similar to the Excel mathematical and trigonometric functions. This section lists the mathematical functions provided by DAX.

The numeric data types used by DAX functions are described in the section, Data Types Supported in PowerPivot Workbooks.
