What does .9 have to do with being a fraction? What if you had the 
number 1.5? This is also a fraction - 3/2. I would recommend something 
like this. 
:A/B
:If fPart(Ans)=0
:Then
:Disp "YES
:Else
:Disp "NO
:End

You could also use the int( command. 
:If A/B=int(A/B
:Then
:Disp "YES
......

Just what is the program for, anyway?
