Title: incorrect math computations on c750 under cacko 1.20
Post by: rcm on March 20, 2004, 11:37:29 am

Has anyone else observed this? Using NeoCal which comes with
the 1.20 Cacko distribution, try taking the square root of 8;
it is 4.000 !
However, other numbers work correctly!
wow, no idea what is wrong, but I am hesitant to use the calculator at
this point ...

I\'ve just checked and noticed that too!  Looks like the Fast FPE amulator is way too inaccurate... I will revert to the default one it from the next ROM version.

maslovsky,
any idea when the 1.20 rom will be upgraded to fix the math bug?
there is a package called \"paranoia\" from www.netlib.org which can
be used to check math functions ...
thanks much

ROM 1.21 includes original FPE emulator, so all computations should be correct.
