/**
 * \defgroup CUDA_MATH Mathematical Functions
 *
 * CUDA mathematical functions are always available in device code.
 *
 * Host implementations of the common mathematical functions are mapped
 * in a platform-specific way to standard math library functions, provided
 * by the host compiler and respective host libm where available.
 * Some functions, not available with the host compilers, are implemented
 * in crt/math_functions.hpp header file.
 * For example, see ::erfinv(). Other, less common functions,
 * like ::rhypot(), ::cyl_bessel_i0() are only available in device code.
 *
 * CUDA Math device functions are no-throw for well-formed CUDA programs.
 *
 * Note that many floating-point and integer functions names are
 * overloaded for different argument types. For example, the ::log()
 * function has the following prototypes:
 * \code
 * double log(double x);
 * float log(float x);
 * float logf(float x);
 * \endcode
 *
 * Note also that due to implementation constraints, certain math functions
 * from std:: namespace may be callable in device code even via explicitly
 * qualified std:: names. However, such use is discouraged, since this
 * capability is unsupported, unverified, undocumented, not portable, and
 * may change without notice.
