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 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 to determine if you can run these functions on a specific accelerator.
