Picbasic Pro divide problem

[Darrel Taylor]

Yes, R2 is one of PBP's internal "System Registers" and if not used immediately the value would be changed.

Floating point is overrated, and not normally required.
Decimal places can usually be dealt with using integer math.

If fctr is a variable and the value is *1000 (2266 = 2.266), then you can just multiply the pulses by the same amount and use DIV32.

    circ = puls * 1000
    circ = DIV32 fctr

This one takes longer to execute and uses more code space than the previous example.

Hi Darrel , thanks again. I used your DIV32 remainder tip to do the rounding to 1mm.
I still have enough flash for my refinements
circ = puls * 1000
circ = (DIV32 fctr)
@ MOVE?WW R2, _Remainder ; Get remainder of Div32
if remainder*10/fctr>4 then circ=circ+1

Great!

Nice addition Hebe.

Darrel, you are a very cleaver guy!
