6.2.58 csinf Function

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

Include

<complex.h>

Prototype

float complex csinf(float complex z);

Argument

z

value for which to return the complex sine

Return Value

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

Example Output

The complex sine of -2.000000 + 1.000000i is -1.403119 + -0.489056i
