JavaScript Operator: exponentiation
[this page | pdf | back links]
In JavaScript,
the ** operator is
the (binary) arithmetic operator for exponentiation.
For example, if x is 8
then y = x ** 5 results in y becoming 32768.
Note: older browsers may
not recognise this operator or the **=
operator, in which case the Math.pow()
method would need to be used.
