6.2.70 ctanhf Function

Calculates the complex hyperbolic tangent function of a single precision complex value.

Include

<complex.h>

Prototype

float complex ctanhf(float complex z);

Argument

z

value for which to return the complex hyperbolic tangent

Return Value

Returns the complex hyperbolic tangent 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)
{
  float complex x, y;

  x = -2.0 + 1.0*I;
  y = ctanhf(x);
  printf("The complex hyperbolic tangent of %f + %fi is %f + %fi\n", crealf(x), cimagf(x), crealf(y), cimagf(y));
}

Example Output

The complex hyperbolic tangent of -2.000000 + 1.000000i is -1.014794 + 0.033813i
