ccosh Function

Calculates the complex hyperbolic cosine function of a double precision complex value.

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




double complex ccosh(double complex z);


value for which to return the complex hyperbolic cosine

Return Value

Returns the complex hyperbolic 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)
  double complex x, y;

  x = -2.0 + 1.0*I;
  y = ccosh(x);
  printf("The complex hyperbolic cosine of %f + %fi is %f + %fi\n", creal(x), cimag(x), creal(y), cimag(y));

Example Output

The complex hyperbolic cosine of -2.000000 + 1.000000i is 2.032723 + -3.051898i
