Post by thread:Copy of: Re: 24 bit FLOATING POINT ROUTINES

Hello I am using V1.18 of the 16c64 24 bit f.p. routines and have so far found 2 problems:- 1. The INT2424 routine dosn't seem to work for the case where the baised exponent is h'90' 2. FPA24 has a problem which is showing up in a addition/divide routine I'm using to give an average of several numbers. I'm not sure why, but for example, adding together:- h'8c7f7f' + h'8c7f7f' gives h'8d7f7f' which is correct, but h'8c7f80' + h'8c7f80' gives 8c7f00' which is wrong. I've cured problem 1. but still need to look at 2. - has anyone found the same problem? The 24 bits routines give reasonable accuracy in my application for a 5 digit indicator - displayed numbers using all 5 digits are sometimes rounded by the LSD or so - using the 32 bit versions would cure this but take more memory - it's a hard life:-) Hope this helps.
