The expfunction in C language Calculates the exponential function e raised to the power of the specified number.

The exp function computes e raised to the power of x, where e is the base of natural logarithms (approximately 2.71828). This function is fundamental in many areas of mathematics and science, including compound interest calculations, radioactive decay modeling, and solution of differential equations.

The expfunction takes 1 parameter:

•
double `x`: The input value for which the exponential function e^x is computed

Computes the base-e exponential function of the given value `x`, returning e raised to the power of `x` as a `double`. This is often used in mathematical and scientific computations.

The exp function return value :

Returns e raised to the power of x
If the result overflows, the function returns HUGE_VAL (with the appropriate sign)
If the result underflows, it returns 0

Output

This example demonstrates the basic usage of the `exp` function for various input values, showing how the exponential function behaves for positive, negative, and zero inputs.
