ccosf Function

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

Attention: This function is implemented only by MPLAB XC32 C compilers.




float complex ccosf(float complex z);


value for which to return the complex cosine

Return Value

Returns the complex cosine of z.


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 = ccosf(x);
  printf("The complex cosine of %f + %fi is %f + %fi\n", crealf(x), cimagf(x), crealf(y), cimagf(y));

Example Output

The complex cosine of -2.000000 + 1.000000i is -0.642148 + 1.068607i
