Sounds like we're both former IBM mainframe programmers. :-)  The same 
systems had (and still have) hexadecimal floating point - the values are 
M*(16^S), not M*(10^S) as in IEEE.  

Of course, the latest machines in that family also have IEEE floats (thanks 
to Java and the scientific Fortran community) and instructions that covert 
between the two formats.  Such things make a hypothetical htonf() routine
