SMSQ/E and Minerva say:

I have a strange question about float number:
what are the maximal and minimal values for a float, on the QL.
I have found the answer for Abacus (it's in the doc!), but
not for the SBasic/whole system.
Il me semble qu'à l'origine la pub parlait 10^512 et 10^-512 ou quelque
chose comme ça (qui n'a guère de sens avec seulement 7 chiffres
significatifs)

That's easy for you to say :o)
I thought it was about 10^604

That should be from 1E-620 to 1.615850285E616.

The M68000 Family Programmer's Reference Manual (which covers the
68040) states the range of a double precision real as 2.2 x 10^-308 to
1.8 x 10^308. It is an eight byte format as shown:

the problem is a bit more than simply QPC x86 code against m68k.
SMSQ is written in 68000 assembly and even rewriting it to make
use of 68020-60 arithmetic would be a major task, not to mention
the lack of suitable assembler for it.

I meant in addition to THAT one!
Using school maths I get:
7 div 3 , 7 mod 3 = 2 , 1
-7 div 3 , -7 mod 3 = -2 , -1
7 div -3 , 7 mod -3 = -2 , 1
-7 div -3 , -7 mod -3 = 2 , -1
Don't forget that under Modulo 3, the numbers -1 and 2 are equivalent.

Thanks for trying to help. Unfortunately the EC version is too crippled to
run SMSQ/E or Linux.
