But yes, in C/C++, a byte is 8 bits wide.

No, the number of bits in a C++ byte is undefined.

You mean the number of bits in a C++ char? Because byte is defined to be 8 bits, much like nibble is defined as 4 bits, independ of the platform or the language.

In C++ a char is defined to be one byte. A byte is not neccessarily 8-bits, although for all intents and purposes you are probably safe assuming that nowadays. Likewise, a nybble is defined to be half a byte, not neccessarily four bits.

In any case, I think we''re all agreed that the answer to the OP is sizeof(float), at least in C++.

(I don''t really know if there is an "official" definations for byte, nybble, et cetera, so I''m basically going off of foldoc.org''s entries for the same).
