But these are... Pascal (Jensen & Wirth) integer X integer --> integer MODULA-2 (Wirth) integer X integer --> integer PostScript (Adobe) integer X integer --> integer Common Lisp (Steele) number X number --> number Tcl (Ousterhout) real X real --> real (fmod()) C (Harbison & Steele) double X double --> double (fmod()) Mathematica (Wolfram) number X number --> number LabView number X number --> number (Q&R) (Some of these have slightly differing meanings.) I don't think we can say there is a convention. If the Revolution mod function works as expected for two positive whole numbers (less than 15 digits), what do we care if it does something useful for other numbers?
