6.2.67 ctanf Function

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

Include

<complex.h>

Prototype

float complex ctanf(float complex z);

Argument

z

value for which to return the complex tangent

Return Value

Returns the complex 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 = ctanf(x);
  printf("The complex tangent of %f + %fi is %f + %fi\n", crealf(x), cimagf(x), crealf(y), cimagf(y));
}

Example Output

The complex tangent of -2.000000 + 1.000000i is 0.243458 + 1.166736i
