# Concurrency::precise_math Namespace

**Visual Studio 2015**

Functions in the **precise_math** namespace are C99 compliant. Both single precision and double precision versions of each function are included. For example, **acos** is the double-precision version and **acosf** is the single-precision version. These functions, including the single-precision functions, require extended double-precision support on the accelerator. You can use the accelerator::supports_double_precision Data Member to determine if you can run these functions on a specific accelerator.
