[e2e] OT: a different number base

[David P. Reed]

PL/I had two number bases in its formal abstract semantic definition, 
decimal and binary.   If you read the original "abstract semantics" specs 
documents published by IBM in about 1969 (I don't think I have mine 
anymore, I bet I could find one through friends though) they REALLY tried 
very hard to make sure that the float decimal and fixed decimal data types 
emulated the quirks of decimal machines in terms of precision, etc.
