The 360 MDL 44 also had no decimal instructions. My question... Is in regards to the various sets of floating point instructions. Is there a tutorial available which demonstrates to and from other number forms, getting your result in printable form etc. Ideally with examples like commonly used spreadsheet functions like =PMT?
