It's just that easy.
Darn, now I'm going to have to do some more homework. And I thought I had explained that, to somebody, once.
In the old days (even before M$ exclude) we solve that with 0.0 and with a '+' or '-' before a number. Later with a '$' for monitary sum.
The rest of that solution is some where in my old memory bank poluted with a lot of coffee. It will come back to me though. Was this a test of some sort? Geeze I think I seen this some where else.
