C++ Math pow()

This function is used to find the power of a given number.

Consider a base ‘b’ and exponent ‘e’.

Syntax

Its syntax would be :

Note: If any argument is of long double type, then the return type is promoted to long double. If not, then the return type is promoted to double.

Parameter

b: ‘b’ is the number, whose power is to be calculated.

e: ‘e’ is the exponent.

Return value

It returns the base ‘b’raised to the power ‘e’.

Example 1

Let’s see a simple example when both base and exponent are of integer type.

Output:

Power of a given number is :16  

Example 2

Let’s see a example when base is of float type and exponent is of integer type.

Output:

Power of a given number is :64  

Example 3

Let’s see a simple example when both base and exponent are of float type..

Output:

Power of a given number is :4
