JS numbers are 64 bits doubles. That means you can't represent 64 bit integers with them because they're only exact for integers up to 2^53. To illustrate: $ node > Math.pow(2, 53) === Math.pow(2, 53) - 1 false > Math.pow(2, 53) === Math.pow(2, 53) true > Math.pow(2, 53) === Math.pow(2, 53) + 1 true -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
