Re^3: Why is Zero not 0?

I think that, so long as the number is less than zero && the number rounds to zero, then we get a leading "-0". Hence:

C:\C>perl -e "printf \"%0.2f\", -0.0049"
-0.00

C:\C>perl -e "printf \"%.0f\", -0.499"
-0

Yes, that's a clearer way of putting it. Note that it's only true for %f formatting, though: `$ perl -e'printf("%d,%0.f\n",-0.1,-0.1)' 0,-0` [download] "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l]
