+2  Q: 

Javascript parseInt with radix 16 issue

The alert statement alert(parseInt("0x00C02700010004E9",16)); incorrectly displays 54086076498707690 instead of the correct value 54086076498707689. Please notice the last two digits!!

Could anyone shed some light on what am I doing wrong?

+2  A: 

Yes! Javascript is not accurate to that many digits! See: http://stackoverflow.com/questions/1379934/large-numbers-erroneously-rounded-in-javascript
