The pow.exponent() function is used to specify the exponent to the given value. It returns the current exponent when the exponent is not specified. The value of the current exponent defaults to one.
Syntax:
pow.exponent( exponent )
Parameters: This function accepts one parameter as mentioned above and described below.
- exponent: This parameter accepts a numeric value that sets the current exponent to the given value. It is an optional value.
