# conjl Function

Calculates the complex conjugate 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 conjl(long double complex z);

Argument

 z value for which to return the complex conjugate

Return Value

Returns the complex conjugate of z, being the value of the argument with the sign of the imaginary part reversed.

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 = conjl(x);
printf("The complex conjugate of %Lf + %Lfi is %Lf + %Lfi\n", creall(x), cimagl(x), creall(y), cimagl(y));
}


Example Output

The complex conjugate of -2.000000 + 1.000000i is -2.000000 + -1.000000i
