Macros
#define	M_PI 3.14159265358979323846

#define	ARCH_MIN_FLOAT_EPS_SQR 0.000244141F
	This is the smallest value e such that 1+e^2 == 1, using floats.

Functions
long	ArchSign (long val)
	Three-valued sign. Return 1 if val > 0, 0 if val == 0, or -1 if val < 0.

uint32_t	ArchFloatToBitPattern (float v)
	Returns The IEEE-754 bit pattern of the specified single precision value as a 32-bit unsigned integer.

float	ArchBitPatternToFloat (uint32_t v)
	Returns The single precision floating point value corresponding to the given IEEE-754 bit pattern.

uint64_t	ArchDoubleToBitPattern (double v)
	Returns The IEEE-754 bit pattern of the specified double precision value as a 64-bit unsigned integer.

double	ArchBitPatternToDouble (uint64_t v)
	Returns The double precision floating point value corresponding to the given IEEE-754 bit pattern.

void	ArchSinCosf (float v, float s, float c)
	Computes the sine and cosine of the specified value as a float.

void	ArchSinCos (double v, double s, double c)
	Computes the sine and cosine of the specified value as a double.

int	ArchCountTrailingZeros (uint64_t x)
	Return the number of consecutive 0-bits in `x` starting from the least significant bit position.
