exp function in C programming language
Description
In C programming language, exp function in C. returns the value of e raised to the xth power.
exp() : In the C programming language, The exp() function calculates e raised to the power of x(given argument)
( calculate the exponential “e” to the xth power)
Declaration
The declaration of the exp() function in the C Language
double exp (double value);
Parameter or argument
the parameter of the exp() function is
x – This is the floating point value
The argument for exp() can be any value, either positive or negative
Returns
The exp() function returns the result of e raised to the power of x
Required header
In the this Language, the required header of the exp() is:
#include<math.h>
exp function in C
Example
The following example shows the usage of the exp function
#include <stdio.h>
#include <stdlib.h>
int main()
{
double x=2.1,y=1;
printf("exp value of %f is %f\n",x,exp(x));
printf("exp value of %f is %f\n",y,exp(y));
getch();
return 0;
}
When the above program is compiled, it will produce the following result
exp value of 2.100000 is 8.166170
exp value of 1.000000 is 2.718282
Program 2
#include <stdio.h>
#include <math.h>
int main()
{
double m,n;//diclare of local variable
printf("Enter the a value for find exponential :");
//get input for calculate sinh
scanf("%lf",&m);
printf("Enter the a value for find exponential :");
//get input for calculate sinh
scanf("%lf",&n);
printf("exp value of the %lf is: %lf\n",m,exp(m));
printf("exp value of the %lf is: %lf",n,exp(n));
getch();
return 0;
}
When the above program is compiled, it will produce the following result
Enter a value for find exponential :2 Enter a value for find exponential :4 exp value of the 2.000000 is :7.389056 exp value of the 4.000000 is :54.598150
