Negative integers

[nntpman68]

Hi,

Dan's solution is probably the clearest.


Just out of curiousity:.

How would you in your program's context like 0 to be treated.

should it be treated as a positive number or should it be treated as
a case part.

my suggestion a*b > 0 for example
wouldn't work if you want 0 to be treated as positive number or if you
compare 0 with 0 and want 'same sign' as answer

bye
