Often enough, the goal isn't only to validate that a number exists, but
to use that number for something.  I've been using Barbara Morris'
GETNUM for many years because it converts character fields containing
decimal points, commas, dollar signs and negative signs.

I have long since lost the original article where it was published but
fortunately it's in the wiki:
