Re: [Flashforth-devel] Floating point math for FF 5.x

[Mikael N. <mik...@fl...>]

I loaded your float number conversion routines just to check out the FP 
binary format.

I noticed that you can skip DO..LOOP in favour of FOR NEXT and it even 
simplifies  the code since 0 FOR NEXT just skips the loop completely.

So for example:

: flshiftn ( d-significand n-exponent n-times -- d n )
   ?dup 0> if 0 do flshift loop then ;

becomes:

: flshiftn ( d-significand n-exponent n-times -- d n )
   for flshift next ;

All the loops in the FP code simply loop a fixed amount of times, which 
nicely suits the FOR NEXT.

Anyway, I started to port Leons >float routine to FlashForth.

Have you seen any other >float routines than Leons, that could be 
checked out ?
