Description

Any number in ActionScript that exceeds the allowed negative numeric range is represented by the numeric constant -Infinity. The smallest negative value (the one with the largest absolute value) allowed in ActionScript is -Number.MAX_VALUE, which is equivalent to -1.7976931348623157e+308.

Example

The result of a calculation that is smaller than (i.e., more negative than) the smallest allowed negative number is -Infinity. For example:

-Number.MAX_VALUE * 2;    // Yields -Infinity

-Infinity also results when dividing a negative number by zero:

-1000 / 0;                // yields -Infinity

Usage

-Infinity is shorthand for Number.NEGATIVE_INFINITY.
