The IBM 1401 Fortran compiler 1401-FO-050 (subset of Fortran II)
generated machine code for integer operations, and bytecode for
floating point. The machine didn't have any floating-point hardware.
The bytecode was smaller than subroutine calls would have been.
Floating-point arithmetic was rather well done. Up to 20 decimal
digits, with two guard digits. Only significant defect was that
rounding wasn't symmetric. Gary Mokotoff did a very good job. I have
the source code if anybody wants it.
