tanh Example
/* Example using tanh by TechOnTheNet.com */
#include <stdio.h>
#include <math.h>
int main(int argc, const char * argv[])
{
/* Define temporary variables */
double value;
double result;
/* Assign the value we will find the tanh of */
value = 0.5;
/* Calculate the Hyperbolic Tangent of value */
result = tanh(value);
/* Display the result of the calculation */
printf("The Hyperbolic Tangent of %f is %f\n", value, result);
return 0;
}
When compiled and run, this application will output:
