# ccoshl Function

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

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

Include

<complex.h>

Prototype

long double complex ccoshl(long double complex z);

Argument

 z value for which to return the complex hyperbolic cosine

Return Value

Returns the complex hyperbolic cosine 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)
{
long double complex x, y;

x = -2.0 + 1.0*I;
y = ccoshl(x);
printf("The complex hyperbolic cosine of %Lf + %Lfi is %Lf + %Lfi\n", creall(x), cimagl(x), creall(y), cimagl(y));
}


Example Output

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