signed number in rm and mf

I have a microfocus cobol program that is reading an rm file. One of the "columns" is a S9V9999 field. if the rm world I would copy it to a pic 99.9999 and the value is readable. 

The value 0050{ gets converted to 0.0500 in rm and 0.0511 in microfocus.

Any one dealing with a similar issue. I'm looking at how rm encodes signed numbers and will continue to post on this.
