Force number format on measure in variable

[setis]

I am using the following measure to dinamically generate a string

Case development = 
VAR LY = [NrCases(Var LY SM CD)]
VAR LM = [NrCases(Var MTD LM CD)]
VAR OvUndLM = IF(LM >0 , "over", "under")
VAR OvUndLY = IF(LY >0 , "over", "under")
RETURN
"The Nr of cases is currently " & LM & " " & OvUndLM & " last month and " & LY & " " & OvUndLY & " the same month last year"

My problem is that the measures [NrCases(Var LY SM CD)] and [NrCases(Var MTD LM CD)] are showing up in the result as decimal numbers, even though I have them formatted as percentages. 

Can I use FORMAT on the variables to force the format as percentage?

Thanks in advance

@setis , format these measures here. As they become part of the text, their value which is <= 1 might be taken.
