6.2.38 cexpl Function

Calculates the complex base-$e$ exponential of a long double precision complex value.

Include

<complex.h>

Prototype

long double complex cexpl(long double complex z);

Argument

z

value for which to return the complex base-$e$ exponential

Return Value

Returns the complex base-$e$ exponential of z.

Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <stdio.h>
#include <complex.h>

int main(void)
{
  long double complex x, y;

  x = -2.0 + 1.0*I;
  y = cexpl(x);
  printf("The complex base-e exponential  of %Lf + %Lfi is %Lf + %Lfi\n", creall(x), cimagl(x), creall(y), cimagl(y));
}

Example Output

The complex base-e exponential of -2.000000 + 1.000000i is 0.073122 + 0.113881i
