| Summary | #include <math.h> double tanh ( double x); /* value to calc hyperbolic tangent for */ |
| Description | The tanh function calculates the hyperbolic tangent for the floating-point value x. |
| Return Value | The tanh function returns the hyperbolic tangent of x. |
| See Also | |
| Example |
#include <math.h>
#include <stdio.h> /* for printf */
void tst_tanh (void) {
float x;
float y;
float pi;
pi = 3.14159;
for (x = -(pi/4); x < (pi/4); x += 0.1) {
y = tanh (x);
printf ("TANH(%f) = %f\n", x, y);
}
}
