cexp(3M)

DESCRIPTION

These functions are available only for IA-64.

cexp() returns the complex base-e exponential of z.

cexpf() is a float complex version of cexp(); it takes a float complex argument and returns a float complex result.

USAGE

To use these functions, compile with the default -Ae option. Make sure your program includes <complex.h>. Link in the math library by specifying -lm on the compiler or linker command line.

RETURN VALUES

cexp(conj(z)) = conj(cexp(z)).

cexp(±0+i0) returns 1+i0.

cexp(x+iInf) returns NaN+iNaN and raises the invalid floating-point exception, for finite x.

cexp(x+iNaN) returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite x.

cexp(+Inf+i0) returns +Inf+i0.

cexp(-Inf+iy) returns +0(cos(y)+isin(y)), for finite y.

cexp(+Inf+iy) returns +Inf(cos(y)+isin(y)), for finite nonzero y.

cexp(-Inf+iInf) returns ±0±i0 (where the signs of the real and imaginary parts of the result are unspecified).

cexp(+Inf+iInf) returns ±Inf+iNaN and raises the invalid floating-point exception (where the sign of the real part of the result is unspecified).

cexp(-Inf+iNaN) returns ±0±i0 (where the signs of the real and imaginary parts of the result are unspecified).

cexp(+Inf+iNaN) returns ±Inf+iNaN (where the sign of the real part of the result is unspecified).

cexp(NaN+i0) returns NaN+i0.

cexp(NaN+iy) returns NaN+iNaN and optionally raises the invalid floating-point exception, for all non-zero numbers y.

cexp(NaN+iNaN) returns NaN+iNaN.

ERRORS

No errors are defined.
