    Since PBP cannot deal with decimal you have to overcome the limitation in this way:

    dc = 100/5 (dc=20)

    LCDOUT $FE,1 ,"0.0",#dc

    display 0.020

    Just as before, 1/8 *1000 = 125, do this because PBP only does integer math, this gives you the answer 125. Display as before LCDOUT $FE, 2, "0."#dc , Or as a European display LCDOUT $FE,2,"0,"#dc .

    Must be that "new math" , .20, you can display that as a string by putting it in quotes, LCDOUT $FE, 2, "1/5" , or as Al pointed out LCDOUT $FE,1 ,"0.",#dc , where the STRING "0." are just symbols for you humans to get your mind around and the real data follows from #dc
