You could look at file fp-bit.c (in gcc/config) or floatlib.c (in dir.
gcc) in gcc sources http://egcs.cygnus.com/.


You can find another code in COCOM toolset (package IEEE in
Ammunition) which is placed on
http://www.linuxstart.com/~vladimir_makarov/download.html


The first implementations are simpler and faster.


The second implementation is more accurate (rounding, NaN, quite NaN,
status bits, sticky status bits, exceptions, trap masks). This
implementation can be easily used to implement 128-bit floating point
numbers because it is based on another package arithm (multiple
precision arithmetic).
