[REBOL] Testing if a string is an integer?
From: mat::eurogamer::net at: 8-Dec-2000 14:27
Folks,
This is a dead basic one and I'm sure I'll feel stupid when someone
points it out.
Anyway, I have a function which is fed a string. Now I'd like to test
to see if the string is purely numerical.
I guess parse is the right way of doing it and I've seen examples but
something basic like
digits: charset [1234567890]
parse number [digits]
type? and so on appears useless since I KNOW it's a string. I even
tried using error? try[] to trap an error converting to an integer -
no luck with that either.
