937.0. "Extended-Precision Multiply and Divide" by CAROL::FRAMPTON (Carol Frampton) Tue Sep 27 1988 15:21

    I am looking for routines to emulate the VAX instructions EMUL
    (extended-precision multiplication) and EDIV (extended-precision
    divison), written preferably in C.  Does anybody know if these exist
    somewhere?  If not, are the instructions speced somewhere so that I
    could implement them myself?

    My guess as to what's wrong with them would be:  They only exist on
    VMS.

These VAX instructions are defined by the VAX Architecture, DEC STD 032.
