Compiler Speed Trials

[boriel]

I tested tobos with

let v=SIN(i)
let v=i^2
let v=LN(i)

instead of numbers that could be replaced with fixed constants (sin (2) could be replaced, for example). It ran in 0.74 seconds instead of the 0.5 for constants. I don't think it's cheating.

When I did the same thing with ZX Basic, it took :!: 24 seconds, instead....

Ok, this is more in consonance with the FP-CALC Rom. The FP ROM CALC is very powerful... but slow. Tobos and SOFTEK are using their own optimized FP routines so they should get more memory and/or less precision. I have some 3 bytes mantisa FP calc routines (ZX Basic uses 4 bytes) for Z80, or program my ones, but this would require a lot of testing and I don't know if it would worth the hassle). E.g. who will use FP for games?
