Hi,
Think of the ** operator as multiplying by units of 1/65536. 0.6*65536=39322.

As for printing to second line of the LCD you're obviously using some sort of serial interface display(?) which I know nothing about but if I'd make a guess based on your defined constants you'd do something like
Code:
HSEROUT[LCD_INST, LCD_L2, "2d Line"]
