Not sure, but would this work?

=MAX(A1-1,0)

Hi
If A1=1, the result could either be 1 or 0.5. I haven't figured out how I
am going to deal with this yet, but the formula you gave me works great.
Thank you Michael!

Hi
What happens when A1 =1 ??
I have allowed for this in the formula below by having A1 <= to 1
Put this in B1
=IF(A11,A1-1,IF(A1<=1,0,""))

minus 1 and if a1 equals less than 1 then b1 will equal zero.
