Functions
template<class T >
T	ceildiv (T num, T den)
	Ceiling of a positive integer division, templated over int types.
template<class T >
T	floorMultiple (T num, T den)
	Return largest multiple of den smaller than num, templated over int types.
__hostanddev__ double	real (const complex &c)
	real part
__hostanddev__ double	imag (const complex &c)
	imaginary part
__hostanddev__ double	norm (const complex &c)
	absolute value squared
__hostanddev__ double	abs (const complex &c)
	absolute value
__hostanddev__ double	arg (const complex &c)
	argument (phase angle)
__hostanddev__ complex	conj (const complex &c)
	complex conjugate
__hostanddev__ double	conj (const double &c)
	identity operation provided to ease templating over complex and double
__hostanddev__ complex	operator+ (double r, const complex &c)
__hostanddev__ complex	operator- (double r, const complex &c)
__hostanddev__ complex	operator* (double r, const complex &c)
__hostanddev__ complex	cis (double x)
	Compute cis(x) = exp(iota x) = cos(x) + iota sin(x)
