Title: Mtgox using single precision float for bitcoin? Post by: gmaxwell on June 03, 2011, 06:25:56 AM I put in a sell order for 1 BTC on MTGOX at 1e120, just to see what the limit was. The system now reports I have an open order at 3.40282e+38.
This doesn't fill me with confidence. Might make some of the weird rounding on orders I've heard people complain about in IRC make more sense... Title: Re: Mtgox using single precision float for bitcoin? Post by: Astro on June 03, 2011, 07:00:54 AM yikes

Me either... why wouldn't they use double precision? Title: Re: Mtgox using single precision float for bitcoin?

Floating point is for when you don't know how many decimal places you need. With Bitcoin you know exactly how many you need; Mt. Gox should not use floating point at all. |
