complex -- complex arithmetic

DESCRIPTION

These functions support complex arithmetic in the C math library.

Each of the following double complex functions has a float complex counterpart with an 'f' appended to the name and a long double complex coun- terpart with an 'l' appended. As an example, the float complex and long double complex counterparts of double cabs()(double complex z) are float cabsf()(float complex z) and long double cabsl()(long double complex z), respectively.
