Description
Math.pow( )
computes
x
to the power of
y
. Any values of
x
and y
may be
passed to Math.pow( )
. However,
if the result is an imaginary or complex number, Math.pow( )
returns NaN
. In practice, this means that if
x
is negative,
y
should be a positive or negative
integer. Also, bear in mind that large exponents can easily cause
floating-point overflow and return a value of Infinity
.
