Certainly! The exp() function in C++ is used to calculate the exponential value of a given number. It raises the mathematical constant e (approximately 2.71828) to the power of the argument.
Here's an example code snippet that demonstrates the usage of the exp() function:
#include <iostream>
#include <cmath> // Required for the exp() function
int main() {
double num = 2.5;
double result = exp(num);
std::cout << "Original number: " << num << std::endl;
std::cout << "Exponential value: " << result << std::endl;
return 0;
}
In this example, we include the <cmath> header file which provides the exp() function. We declare a double precision floating-point variable num and assign it a value of 2.5.
By calling exp(num), we calculate the exponential value of num. In this case, the result will be the mathematical constant e (approximately 2.71828) raised to the power of 2.5. We store this result in the variable result.
Finally, we print the original number and the exponential value using std::cout.
The output will be:
Original number: 2.5
Exponential value: 12.1825
As you can see, the exp() function provides a way to calculate the exponential value of a number in C++.
