If you must have floating points there is a routine over at the MeLabs site.

The easy way for what you are doing is to drop the decimal point.
x = 2 * 1.5

would be
x = 2 * 15 / 10

Then if you are wanting to display a 3.0
Code:
LCDOUT, $FE;1,DEC x,".",DEC2 x//100
65535 is the largest value for a WORD size variable. So 125000 over flows, comes back around starting at zero and the result is 59464.
