exp in c

What is exp in c programming?

exp function calculates exponential value of a given number.

It is defined in math.h header file.

Prototype

double exp(double m);

Parameters

exp function takes double type value as input parameter.

Return values

exp function returns exponential value of a given number.


Example program for exp in c

#include<stdio.h>
#include<math.h>
int main()
{
 double a=2.0;
 printf("The exponential value is %lf \n",exp(a));
 return 0;
}

Difference between exp and pow in c

exp function is used to calculate the exponential value of a given number. pow is used to calculate the power of a number raised to the base value.

exp function takes one parameter. pow function takes two parameters.

Prototypes are as follows

double exp(double value1);

double pow(double value1,double value2);
