Calculates the complex tangent function of a single precision complex value.
Include
<complex.h>
Prototype
float complex ctanf(float complex z);
Argument
z |
Return Value
Returns the complex tangent 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)
{
float complex x, y;
x = -2.0 + 1.0*I;
y = ctanf(x);
printf("The complex tangent of %f + %fi is %f + %fi\n", crealf(x), cimagf(x), crealf(y), cimagf(y));
}
Example Output
The complex tangent of -2.000000 + 1.000000i is 0.243458 + 1.166736i
