Boolean Algebra

    I'm developing a system and need to express part of the design for it using Boolean Algebra. This will go into a formal document.

    However, there are a number of notation styles:

    AND: ^ . &
    OR: v + ||
    NOT: ¬ ! ~


    Is there a subset of these which are the recognised symbols or how do I choose which to use? I've grown up using . + !
    However, I thought this would have been standardised by now. Otherwise I'll have to put a key into the document to the symbols which I'd like to avoid doing.

    I would say it depends on the context, choose one set of symbols and stick with it.

    All developers should recognise &&, ||, ! as they universal boolean operators available in almost every programming language.

    && and || are bitwise operators in certain languages.

    Wiki seems to state that v, ^, ¬ are its primary indications.

    However, this site (random one I know) defines Algebraic Notation as what I would like to use:

    Looks like it is longhand!
