Fileman fields can't be multiples of .10 -- is this a good thing?

[Kevin Toppenberg]

He all, I was making a new Fileman file, and added fields .01, .02, .03 ... .09   But when I tried to enter a field as .10, I was blocked and it wouldn't accept it.

The reason come from N^DICN1 where it tests value via +X=X 

And +".10" = ".1", so it fails this test.  

I guess that means that .10, .20, .30 etc are all disallowed.  I could skip from .09 to .11, but it seems weird to have to skip .10.  Or I could enter .1 and leave it at that....

I'm guessing if I allowed .10, it would break something else, right?

.10 is not a number in M. .1 is.

Bingo! 

An M canonical number will have all leading zeroes removed, and all trailing zeroes after

a decimal point removed, including the decimal point if the removal of trailing zeroes

results in a trailing decimal point. Hence, as Sam said, .10 becomes .1, which is the same

number after all, with no precision lost.

Thanks all.  I just went with .09, .1, .11

I prefer to give fields integer numbers, that way this issue doesn't exist.
(and you can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ...)

My system of numbering fields is based on what IHS did in the 1980s: .13 = .1 node third piece. 1003 = 10, 3rd piece. 1010 = 10, 10th piece, etc.
