    I am glad your code works. But in case you will need one decimal place precision in your calculation, then you can re-work your formula in this way:

    Code:
    Vu  var byte ' unit
Vd var byte  ' decimal

P = 6000 * ad_word / 614
V = SQR(P)
Vu = V DIG 1
Vd = V DIG 0

LCDOUT $FE, 1, Vu,".",Vd
    Cheers
