Abstract

R5RS Scheme has no utilities for performing bitwise logical operations on integers or bitstrings, which is a problem for authors of portable code. This SRFI proposes a coherent and comprehensive set of these functions; it is accompanied by a reference implementation of the spec in terms of a set of seven core operators. The reference implementation is

• portable
• efficient
• completely open, public-domain source

The precise semantics of these operators is almost never an issue. A consistent, portable set of names and parameter conventions, however, is. Hence this SRFI.
