exp Example
/* Example using exp 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 exp of */
value = 5;
/* Calculate the exponential of the value */
result = exp(value);
/* Display the result of the calculation */
printf("The Exponential of %f is %f\n", value, result);
return 0;
}
When compiled and run, this application will output:
The Exponential of 2.100000 is 8.166170
