Type conversion within arithmetic expressions. What does ANSI say ?

[Jeffrey T. Hutzelman]

The ANSI standard does not guarantee the sizes of unsigned char and
unsigned short int; only that sizeof(char)<=sizeof(short).  If you
want to be sure it works, try z=(unsigned short)x * (unsigned short)y
(you may need parens; I'm not familiar with the precedence rules
regarding type casting, but I think it is higher that multiply).
