You may wish to obtain the newest version of DJGPP, v2.01. I don't know the details of the floating point algorithms, but there were a number of bug fixes made to the math library code. The latest versions of all DJGPP tools can be obtained from , in the directories beginning with 'v2'. I suggest you read the file 'v2/readme.1st' before getting anything else, as it details exactly what you need to download and how to install it. There were a lot of changes from v1.12 to v2.x! :) If you still have problems after upgrading, please post some sample code that produces the erroneous output so we can try it ourselves. I also have a 486/66 computer available, so I'd be glad to test it myself. Hope this helps! -- --------------------------------------------------------------------- | John M.
