My "ref"[1] module can do this. It extends Buffer.prototype with the
missing {read,write}{U}Int64{LE,BE] functions by calling into native
functions. It can accept Strings with big integers inside of it and it will
strtoll or strtoull the value in C-land. It also returns Strings when the
value being returned is outside the range of a valid JS Number.Cheers! 1: https://github.com/TooTallNate/ref On Thu, Jun 21, 2012 at 1:04 PM, Tim Caswell <t...@creationix.com> wrote: > Keep in mind that you'll lose precision when converting it to a native > javascript number.
