[REBOL] decimal woes

From: maximo:meteorstudios at: 18-Jul-2003 11:01

Hi all, I am having fun converting SEISMIC data (sampled at 5 thousands of a second :-) within a 30MB file. I must dump all of this in a 3d animation package (maya) and its working... except for one point.. decimal datatype is a little unstable, and maybe someone can tell me why this happens: if you do: time: 0 loop 50 [ time: time + 0.02 probe time ] ask "" at the end you will have 0.92 0.940000000000001 0.960000000000001 0.980000000000001 but if you then do 0.92 + 0.02 you get 0.94 the floating point error gets worse and worse (and eventually diminishes a little!!!) there are only two signifiant digits in all calculus, I am wondering if it could be possible for the floating point algorythms to be a little more stable... I had to an ugly integer calculation workaround divided by 100 to get the clean decimals... -max
