Re: IsNumeric("121d1") = True ??

I was a mathematics major about 22 years ago, but that doesn't mean I know
how to express facts precisely anymore, I guess! When an OP shows a bunch of
numbers all which are positive integers, some expressed in "d" notation, I
say "number of trailing zeros" without even thinking because that is what
they worked out to be in his case: Your additional clarity (and recognizing
the need for it) is appreciated not just by myself, but by all reading the
post I am sure... thanks.
