C language exp() function: find the base e raised to the x power

Function name : exp

Header file : <math.h>

Function prototype : double exp(double x);

Function : Find the base e raised to the x power

Parameters : double x is the index to be operated on

Return value : Returns the base e raised to the power of x

Note : The natural number e is a constant 2.71828

Program example : Find the x power of the base e and output the result

 #include<stdio.h>#include<math.h>intmain(void){doubleresult;doublex=4.0;result=exp(x);printf('e'raisedtothepowerof%lf(e^%lf)=%lf n,x,x,result);return0;}

Running results:

 'e'raisedtothepowerof4.000000(e^4.000000)=54.598150
