fuzzyEquals  ()  method 
public static function fuzzyEquals(number1:Number, number2:Number, precision:int = 5):Boolean
Tests equality for numbers that may have been generated by faulty floating point math. This is not an issue exclusive to the Flash Player, but all modern computing in general. The value is generally offset by an insignificant fraction, and it may be corrected.
Alternatively, this function could be used for other purposes than to correct floating point errors. Certainly, it could determine if two very large numbers are within a certain range of difference. This might be useful for determining "ballpark" estimates or similar statistical analysis that may not need complete accuracy.
Parametersnumber1:Number — number1 the first number to test


number2:Number — number2 the second number to test


precision:int (default = 5 ) — precision the number of digits in the fractional portion to keep

Boolean — true, if the numbers are close enough to be considered equal, false if not.

roundDownToNearest  ()  method 
public static function roundDownToNearest(number:Number, nearest:Number = 1):Number
Rounds a Number down to the nearest multiple of an input. For example, by rounding 16 down to the nearest 10, you will receive 10. Similar to the builtin function Math.floor().
Parametersnumber:Number — the number to round down


nearest:Number (default = 1 ) — the number whose mutiple must be found

Number — the rounded number

roundToNearest  ()  method 
public static function roundToNearest(number:Number, nearest:Number = 1):Number
Rounds a Number to the nearest multiple of an input. For example, by rounding 16 to the nearest 10, you will receive 20. Similar to the builtin function Math.round().
Parametersnumber:Number — the number to round


nearest:Number (default = 1 ) — the number whose mutiple must be found

Number — the rounded number

roundToPrecision  ()  method 
public static function roundToPrecision(number:Number, precision:int = 0):Number
Rounds a number to a certain level of precision. Useful for limiting the number of decimal places on a fractional number.
Parametersnumber:Number — number the input number to round.


precision:int (default = 0 ) — precision the number of decimal digits to keep

Number — the rounded number, or the original input if no rounding is needed

See also
roundUpToNearest  ()  method 
public static function roundUpToNearest(number:Number, nearest:Number = 1):Number
Rounds a Number up to the nearest multiple of an input. For example, by rounding 16 up to the nearest 10, you will receive 20. Similar to the builtin function Math.ceil().
Parametersnumber:Number — the number to round up


nearest:Number (default = 1 ) — the number whose mutiple must be found

Number — the rounded number
