Field Entry Restriction

[Ukyo]

Dear Professionals,

I'd like to restrict certain field so that the user can enter only a certain decimal number.

I only want the users to enter:

1.5,2.5,3.5 and so on. Only x.5

But not:

1.1,2.4,3.7 and so on.

I've tried the Round() function at Auto Enter Calculated Value,

but did not work.

I'd really appreciate if someone can help me out.

X - Int(X) = 0.5

Use this as a "validate by calculation"

something like this may work.

Round ( X / 5 ; 1 ) * 5

Assuming integers are allowed as well, try validating the field by calculation =

not Mod ( 2 * YourField ; 1 )

Thank you all!

raybaudi's calculation best fitted my need this time.

I should have payed more attention in my Math class...
