well in some case it's more easy to do them in integer...

2.45 * 1.45 will become (245 * 145)

and then you do the the rest with DIG and DEC to display as you want.

something like LCDOUT $fe,1, DEC DIG 1 MyVar,".",Myvar DEC4

but i have to agree that it can be usefull to have built-in floating point maths... in some case

as built in real SIN,COS,LOG or many else other.
