@node Complex@chapter Mathematical Complex Functions (@file{complex.h}) This chapter groups the complex mathematical functions.  Thecorresponding definitions and declarations are in @file{complex.h}.  Functions and documentations are taken from NetBSD. @menu * Function cabs::	Complex absolute value* Function cacos::	Complex arc cosine* Function cacosh::	Complex arc hyperbolic cosine* Function carg::	Argument (also called phase angle)* Function casin::	Complex arc sine* Function casinh::	Complex arc hyperbolic sine* Function catan::	Complex arc tangent* Function catanh::	Complex arc hyperbolic tangent* Function ccos::	Complex cosine* Function ccosh::	Complex hyperbolic cosine* Function cexp::	Complex exponent* Function cimag::	Imaginary part* Function clog::	Complex natural (base e) logarithm* Function clog10::	Complex base 10 logarithm* Function conj::	Complex conjugate* Function cpow::	Complex power function* Function cproj::	Compute a projection on the Riemann sphere* Function creal::	Real part* Function csin::	Complex sine* Function csinh::	Complex hyperbolic sine* Function csqrt::	Complex square root* Function ctan::	Complex tangent* Function ctanh::	Complex hyperbolic tangent@end menu @page@include   complex/cabs.def@page@include   complex/cacos.def@page@include   complex/cacosh.def@page@include   complex/carg.def@page@include   complex/casin.def@page@include   complex/casinh.def@page@include   complex/catan.def@page@include   complex/catanh.def@page@include   complex/ccos.def@page@include   complex/ccosh.def@page@include   complex/cexp.def@page@include   complex/cimag.def@page@include   complex/clog.def@page@include   complex/clog10.def@page@include   complex/conj.def@page@include   complex/cpow.def@page@include   complex/cproj.def@page@include   complex/creal.def@page@include   complex/csin.def@page@include   complex/csinh.def@page@include   complex/csqrt.def@page@include   complex/ctan.def@page@include   complex/ctanh.def
