Maximum integer range of Number

Question

We are doing some maths with large integers in Actionscript 3. Because there is no long type, we are using Number.

What's the range of consecutive integers (positive to negative) a Number can accurately represent before it starts to veer into floating point errors?

Answer 1

ActionScript® 3.0 Reference for the Adobe® Flash® Platform states that the Number data type adheres to the double-precision IEEE-754 standard. In IEEE-754 double-precision, there are 64 bits in use (1 for sign bit, 11 bits for exponent and 52 bits for fraction).

Therefor maximum integer range should be approximately ±1.7976931348623157×(10^308)
