SharePoint List - number column restrict values

[neeesz78]

Hello All , 

We've SharePoint LIST column (Number) ,  1 decimal ,  Min Value is 1  , Max Value 3 

I want to restrict users from entering values other than these 5 below

• 1
• 1.5
• 2
• 2.5
• 3 

is there any validation formula which can be used ? 

When data entered here its updating master LIST with number using FLOW 

So,  if I convert to choice column - not sure if Power Automate will pick value and convert to number when updating master LIST  

Thanks

@neeesz78 Use this column validation formula: 

=OR([NumberCol]=1,[NumberCol]=1.5,[NumberCol]=2,[NumberCol]=2.5,[NumberCol]=3)

Where [NumberCol] is name of your number column.
