COMPLEX(3) Library Functions Manual COMPLEX(3) NAME complex -- complex arithmetic LIBRARY Math Library (libm, -lm) SYNOPSIS #include <complex.h> DESCRIPTION These functions support complex arithmetic in the C math library. LIST OF FUNCTIONS Each of the following double complex functions has a float complex counterpart with an `f' appended to the name and a long double complex counterpart 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.

STANDARDS The <complex.h> functions described here conform to ISO/IEC 9899:1999 ("ISO C99"). BUGS The power functions, cpowf,(cpow), and cpowl(), are implemented, but the code was neither reviewed nor tested. FreeBSD 13.2 November 3, 2021 COMPLEX(3)
