Example
The following commented code uses the bitwise right shift and assignment (
>>=) operator.
function convertToBinary(numberToConvert:Number):String {
var result:String = "";
for (var i = 0; i<32; i++) {
// Extract least significant bit using bitwise AND
var lsb:Number = numberToConvert & 1;
// Add this bit to the result
string result = (lsb ? "1" : "0")+result;
// Shift numberToConvert right by one bit, to see next bit
numberToConvert >>= 1;
}
return result;
}
trace(convertToBinary(479));
// Returns the string 00000000000000000000000111011111
// This string is the binary representation of the decimal
// number 479

>> bitwise right shift operator
>>> bitwise unsigned right shift operator
expression1 >>> expression2
The same as the bitwise right shift (>>) operator except that it does not preserve the sign of the
original
expression because the bits on the left are always filled with 0.
Floating-point numbers are converted to integers by discarding any digits after the decimal
point. Positive integers are converted to an unsigned hexadecimal value with a maximum
value of 4294967295 or 0xFFFFFFFF; values larger than the maximum have their most
significant digits discarded when they are converted so the value is still 32-bit. Negative
numbers are converted to an unsigned hexadecimal value via the two's complement notation,
with the minimum being -2147483648 or 0x800000000; numbers less than the minimum
are converted to two's complement with greater precision and also have the most significant
digits discarded.
