Usage of exp in c language

The exp function computes the natural exponent (the power of e) of a given number, where e is a mathematical constant approximately equal to 2.71828. The exp function accepts a parameter x of type double, and the return type is also double. It returns the natural exponent of x, which is e^x.

Usage of exp in C language

#The exp function is a mathematical function in the C standard library. It calculates The natural exponent (a power of e) of a given number. e is a mathematical constant equal to approximately 2.71828.

Usage:

exp The prototype of the function is as follows:

<code class="c">double exp(double x);</code>

It accepts a double type parameter x, indicating that the base of its natural exponent is to be calculated . The function return type is also double.

Return value:

The exp function returns the natural exponent of x, which is e^x.

Example:

The following code example shows how to use the exp function to calculate the natural exponent of 2:

<code class="c">#include <stdio.h>
#include <math.h>

int main() {
  double x = 2;
  double result = exp(x);
  printf("e^%f = %f\n", x, result);
  return 0;
}</code>

This program output:

<code>e^2.000000 = 7.389056</code>

Note:

• The result calculated by the exp function may be very large or very small, so it is important to ensure that the double type is used to store the result.
• exp(0) equals 1.
• exp(x) is always positive.
