Yes.

It's part of standard C for a long time.

The math is done in the same data type as the constants/variables you
use in the expression.  "31" and "1" are constants whose type is
`int', not `'long' or `unsigned long'.  If you want non-default data
types for your constants, you need to use suffixes such as the `U' and
`L'.
