Math Registers in Micrologix 1100

I'm trying to convert a millimeter value to an inch value in a micrologix 1100, writing the program with RSLogix 500. Multiplying the millimeter by 254 and then dividing that by 10 is successfull to a point - but can be off by as much as half an inch because the division result gets rounded.

I've been fumbling around with the division command and figured out that if I set the math register S:13 as the destination, then S:13 will hold the remainder and S:14 will hold the quotient - numbers I should be able to use to get to within .01 of an inch.

The problem I'm having is I can't figure out a command to pull the numbers from the S:13 and S:14 registers into the integer data file where I can store and use it. Could anybody give me a hand?

Why not use floating point data type. Floating point registers.

I think you wrote the math backwards, though it's probably right in your program.

(millimeters * 1000)/254 = inches with 2 implied decimal places

25.4 * 1000 = 25400
divided by 254 = 100 (1.00 inches)

If you use the math registers just MOV the contents

MOV S:13 N7:5 - but do this immediately after the division. Remember that the Dest of the DIV instruction must be S:13 for the remainder stuff to happen.

Or just use floating point.
