COMPLEXF  - Subroutines to perform operations on complex numbers.
		This set of functions complement the one in complex.c
		of the CWP library

cipow		raise a complex number to an integer power
crpow		raise a complex number to a real power
rcpow		raise a real number to a complex power
ccpow		raise a complex number to a complex power
ccos		compute the complex cosine of a complex angle
csin		compute the complex sine of a complex angle
ccosh		compute the complex hyperbolic cosine of a complex angle
csinh		compute the complex hyperbolic sine of a complex angle
cexp1		compute the complex exponential of a complex number
clog		compute the complex logarithm of a complex number
