C Programming Tutorial
C Programming allows us to perform mathematical operations through the functions defined in
C Math Functions
In the C Programming Language, the exp function returns e raised to the power of x.
Syntax
The syntax for the exp function in the C Language is
double exp(double x);
Parameters or Arguments
The value used in the calculation where e is raised to the power of x. If the magnitude of x is too large, the exp function will return a range error.
Returns
The exp function returns the result of e raised to the power of x.
Required Header
In the C Language, the required header for the exp function is:
#include <math.h>
Applies To
In the C Language, the exp function can be used in the following versions
- ANSI/ISO 9899-1990
exp Example
/* Example using exp by c programming */
#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
