Hi,
I used to hack 386BSD, but have been away from it for some months now.
I remember that the Floating Point Unit emulator did not work very well. It
used to give incorrect answers. For example, if I run the following code:
/* test floor */
main()
{
printf("What do I get? Answer: %f\n",floor(10,9));
}
Using the math emulator I got 10,89something (can't recall exact number, but
it was wrong!)
When I put a copro in (I actually used a 287) I got the expected answer.
10.000000. Unfortantly I cannot use the 287 with everything.
My question: Has this been fixed? Or is everyone using 486DX's ?
