show on LCD decimal numbers

[skimask]

i have two variables:
x var word
y var word
and x < y.

How to show on lcd the result of x/y , or the value = SQR x/y

Right...I understand that. I'm still trying to make you understand.
Again, I ask you to do a search in the PBP manual for floating point math and tell me what you come up with (same hint: we've already been through this in January, see post #8 of the "16f877 with LM335 problem" thread ).

I have read the manual for floating point very well and i have see post #8 of the "16f877 with LM335 problem" thread.
i use this:

                                        ' forwardpower  = 400 
                                        ' reflectedpower = 20
    B0 = forwardpower/reflectedpower    ' = 400/20 = 20    
    B1 = 10000/B0                       ' = 10000*1/20 = 500                    
    B2 = SQR B1                         ' = 22,360679    
    B3 = (10000+B2*100)/(100-B2)        ' = (10000+22*100)/(100-22) = 12200/78 = 156,4
    Lcdout $fe,$90, "SWR  : ",DEC (B3 DIG 2),".", DEC (B3 DIG 1),DEC (B3 DIG 0)

So what's the problem? What did you find about floating point in the manual?

now i don't have problem.
I spent many hours , how to solve my problem.
with floating point i solve my problem
