This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
Availability
JavaScript 1.0; JScript 1.0; ECMAScript v1
Synopsis
Math.pow(x, y)Arguments
x
The number to be raised to a power.
y
The power that x is to be raised to.
Returns
x to the power of
y,
xy .
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.
