Number.POSITIVE_INFINITY Constant
Name
Number.POSITIVE_INFINITY Constant---infinity
Number.POSITIVE_INFINITY is a special numeric value
that is returned when an arithmetic operation or
mathematical function generates a value greater than the
largest representable number in JavaScript (i.e., greater
than Number.MAX_VALUE).
JavaScript displays the POSITIVE_INFINITY value as
Infinity. This value behaves mathematically like an
infinity--for example, anything multiplied by infinity is
infinity, and anything divided by infinity is zero.
Note that when numbers "underflow," i.e., when they become
less than Number.MIN_VALUE, JavaScript converts them
to zero.
