Concurrency::precise_math Namespace
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 doubleprecision version and acosf is the singleprecision version. These functions, including the singleprecision functions, require extended doubleprecision 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.
