Synopsis
Number.POSITIVE_INFINITY
Description
Number.POSITIVE_INFINITY is a special numeric
value returned when an arithmetic operation or mathematical function
overflows or generates a value greater than the largest representable
number in JavaScript (i.e., greater than
Number.MAX_VALUE). Note that when numbers
"underflow," or become less than
Number.MIN_VALUE, JavaScript converts them to
zero.
JavaScript displays the POSITIVE_INFINITY value as
Infinity. This value behaves mathematically like
infinity; for example, anything multiplied by infinity is infinity
and anything divided by infinity is zero. In ECMAScript v1 and later,
you can also use the predefined global constant
Infinity instead of
Number.POSITIVE_INFINITY.
