Regex Issure with Decimals and Whole Numbers

[#1]

Hello!

Using JMP 16.2: I have a column with whole numbers and decimal numbers. I want to create a new column that flags the whole numbers (or the decimals). 

Column Name: Value

Column Inputs:

0

.5

3

3.768

10

etc.

I have tried several versions of the following Regex using a column formula:

Regex(Value,"\d+\,\d+", "Decimal")

Regex(Char(Value),"\d+\,\d+", "Decimal")

I have also tried parentheses and brackets throughout the second input.

I also have noticed, if there is a column with ONLY decimals and not whole numbers, the regex works...

Anyone have a useful trick to get this to work?

Thanks!

Do you have a character column or some custom format? Which formats would you allow for decimals values? For example is ".1" valid decimal? And do you have to worry about something else besides those? You might be able to just use Contains(:Value, ".") and check if "." is found from the string

Edit:

Hello! The format for the NEW column is "Numeric" and the source column (Value) is also numeric. There are no characters in the source column.

".1" would not be valid, my mistake, they are marked as "0.1" for numbers <1.

I did try the contain and that is giving me a warning: Contains(:"Value"n,".") 

Error: argument is wrong type

(thanks for the regex site to test my ideas!)

If your source and destination are Numeric columns, then you can use a Boolean expression in a formula in the destination data column

(:Value - Round( :Value, 0 )) == 0

Or

Modulo( :Value, 1 ) == 0

So your table looks like this:

I used the Value Labels column property to display words instead of just 0 or 1.
