RE: [flexcoders] why is trace(1+0.9+0.7+0.3) = 2.8999999999999995

[Gordon Smith]

The short answer is that the Number type can't store most decimal fractions exactly. It stores floating point numbers as binary fractions, so there is usually some roundoff error.   - Gordon   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Michael Schmalle Sent: Monday, March 27, 2006 6:24 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] why is trace(1+0.9+0.7+0.3) = 2.8999999999999995   I could swear there was a thread on this precision issue that Gordon Smith answered and it did have to do with the trace function. Search the archives, I bet you will find it.
