Functions
Fast math
We provide approximate mathematical functions. These are usually rather faster than the corresponding standard library functions.
float_t	VL::fast_expn (VL::float_t x)
	Fast @ exp(-x).
float_t	VL::fast_mod_2pi (VL::float_t x)
	Fast `mod(x,2pi)`.
int32_t	VL::fast_floor (VL::float_t x)
	Fast (int) floor(x).
float_t	VL::fast_abs (VL::float_t x)
	Fast `abs(x)`.
float_t	VL::fast_atan2 (VL::float_t y, VL::float_t x)
	Fast `atan2`.
float	VL::fast_resqrt (float x)
	Fast `resqrt`.
double	VL::fast_resqrt (double x)
	Fast `resqrt`.
float_t	VL::fast_sqrt (VL::float_t x)
	Fast `sqrt`.
