NAME
cexp10(), cexp10f(), cexp10l(), cexp10w(), cexp10q() - complex base-10 exponential functions
SYNOPSIS
#include <complex.h>
double complex cexp10(double complex
z);
float complex cexp10f(float complex
z);
long double complex cexp10l(long double complex z);
extended complex cexp10w(extended complex
z);
quad complex cexp10q(quad complex z);
DESCRIPTION
cexp10() returns the complex base-10 exponential of z.
cexp10f() is a float complex version of cexp10()
; it takes a float complex argument and
returns a
float complex result.
cexp10l() is a long double complex version of
cexp10(); it takes a long double complex
argument and returns a long double complex result.
cexp10w() is an extended complex version of cexp10(); it takes an extended complex argu-
ment and returns an extended complex result.
cexp10q() is equivalent to cexp10l() on HP-UX systems.
USAGE
To use these functions, compile with the default
-Ae option. To use cexp10w()
or cexp10q(), com-
pile with the
-fpwidetypes option. Make sure your program includes <complex.h>. Link in the
math library by specifying -lm on the compiler or linker command line.
RETURN VALUE
cexp10(conj(z)) = conj(cexp10(z)).
cexp10(±0+i0) returns 1+i0.
cexp10(x+iInf) returns NaN+iNaN and raises the invalid floating-point exception, for finite x .
cexp10(x+iNaN) returns NaN+iNaN and optionally raises the invalid floating-point exception, for
finite x .
cexp10(+Inf+i0) returns +Inf+i0.
cexp10(-Inf+iy) returns +0(cos(log(10)y)+isin(log(10)y))
, for finite y .
cexp10(+Inf+iy) returns +Inf(cos(log(10)y)+isin(log(10)y
)), for finite nonzero y .
cexp10(-Inf+iInf) returns ±0±i0 (where the signs of the real and imaginary parts of the result are
unspecified).
cexp10(+Inf+iInf) returns ±Inf+iNaN and raises the invalid floating-point exception (where the sign of
the real part of the result is unspecified).
cexp10(-Inf+iNaN) returns ±0±i0 (where the signs of the real and imaginary parts of the result are
unspecified).
cexp10(+Inf+iNaN) returns ±Inf+iNaN (where the sign of the real part of the result is unspecified).
cexp10(NaN+i0) returns NaN+i0.
cexp10(NaN+iy) returns NaN+iNaN and optionally raises the invalid floating-point exception, for all
non-zero numbers y .
cexp10(NaN+iNaN) returns NaN+iNaN.
