Any fast floating point or fixed point math code available?

Ticks  Math Package

1010   Altirra package in Altirra Basic

 

 

Altirra BASIC doesn't include a math package, it uses the one that's included in the OS like Atari BASIC does. The above looks like it was still using the stock math pack, so it was only benchmarking the difference in the BASIC interpreter, which would have been minimal in this math-heavy test. You'd have to swap the OS for AltirraOS to get the different math pack code. (In general, it's a little bit faster than the Marslett code for multiplies and a bit slower for divides.)

thanks!! I have updated my post.

 

is there a clear winner in the math package race?

This rom uses the Marlett's FastFP package (is this a good one?).

Yes. Note however, that the presence of Marslett's FP code in ROM makes Turbo-BASIC XL work incorrectly - the LOG() and EXP() functions will return meaningless results. I think that not even the TBXL version prepared by @dmsc has this fixed.
