csinl Function

Calculates the complex sine 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 csinl(long double 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)
{
  long double complex x, y;

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

Example Output

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