Description
The pow function calculates the value of the base base raised to the exponent exponent and returns the result.
Syntax
pow(base, exponent)
Arguments
| Argument | Description |
|---|---|
base |
The base of the exponentiation. |
exponent |
The exponent to which the base is raised. |
Return Value
The function returns the result of the calculation baseexponent as a number.
Examples
| Description | Example |
|---|---|
| Square of a number |
pow(3, 2)Result: 9 |
| Cube of a number |
pow(2, 3)Result: 8 |
| Negative exponents |
pow(2, -2)Result: 0.25 |
| Exponent equal to zero |
pow(5, 0)Result: 1 |
Notes
- If the exponent
0is provided, the function always returns1regardless of the base (except when the base is0, which leads to an error). - Negative exponents calculate the reciprocal of the power. For example,
pow(2, -2)equals1 / (22).
