Hi M Carmen,
I asked this very question not so long ago on this newsgroup (probably
around October/November last year) -
you might want to check out that thread. Basically the answer was "never
use a float as the loop variable."
Also, Jeff Hester probably has some helpful :-) comments to pass on. I
know I was particularly encouraged
and assisted by his replies,

Andre
