Even numbers of circ causes weird spacing












3















I noticed when trying to make a string of 6 circ symbols that the last one is closer to the one beside it than the rest of them, after playing with it for a while it looks like an even number (greater than 2) of circ causes this, how can I fix the spacing so it is even?



Example:



documentclass{article}
begin{document}
1 circ: $circ $

2 circ: $circ circ $

3 circ: $circ circ circ$

4 circ: $circ circ circ circ$

5 circ: $circ circ circ circ circ $

6 circ: $circ circ circ circ circ circ $

7 circ: $circ circ circ circ circ circ circ $

end{document}

When you issue showcirc you'll see it defined as mathchar"220E. The first number in this definition points to the intrinsic "format" of the character. 2 denotes a binary operator which has a specific spacing around. So, circ is considered a binary operator and therefore expects operands on either side. Odd-numbered circs show better alignment as they supply "operands" on either side (barring accommodation for uniform spacing around consecutive circs):



enter image description here



documentclass{article}

begin{document}

1 circ: $circ$

2 circ: $circ circ$

2 circ: $circ circ {}$

3 circ: $circ circ circ$

4 circ: $circ circ circ circ$

4 circ: $circ circ circ circ {}$

5 circ: $circ circ circ circ circ $

6 circ: $circ circ circ circ circ circ$

6 circ: $circ circ circ circ circ circ {}$

7 circ: $circ circ circ circ circ circ circ$

end{document}


If you just want to list a number of circs with the correct spacing, consider adding a empty math group at the end when using an even number of circs. Alternatively, use {circ} or mathord{circ} to avoid the surrounding space; mathord turns its argument into a math ordinal.

    From the TeXbook (page 187, solution on page 326)




    Exercise 19.7

    B. L. User tried typing ‘eqno(*)’ and ‘eqno(**)’,
    and he was pleased to discover that this produced the equation numbers
    ‘(∗)’ and ‘(∗∗)’. [He had been a bit worried that they would come out
    ‘(*)’ and ‘(**)’ instead.] But then a few months later he tried
    eqno(***)’ and got a surprise. What was it?



    When you type an asterisk in math mode, plain TeX considers
    * to be a binary operation. In the cases ‘(*)’ and ‘(**)’, the
    binary operations are converted to type Ord, because they don't appear in
    a binary context; but the middle asterisk in ‘(***)’ remains of type Bin.
    So the result was ‘(∗ ∗ ∗)’. To avoid the extra medium spaces, you can
    type ‘eqno(*{*}*)’; or you can change mathcode`*, if you never use
    * as a binary operation.




    It doesn't matter if we're in an equation number (eqno); the main issue is math mode where the behavior shows. Since circ is a binary operation symbol just like *, you get the same.



    If you want evenly spaced circ symbols you can use



    {circ};{circ};{circ};{circ}


    Even better, define a suitable command:



    documentclass{article}
    usepackage{xparse}

    ExplSyntaxOn
    NewDocumentCommand{circs}{m}
    {
    ensuremath
    {{
    {circ}prg_replicate:nn { #1 - 1 } { ; {circ} }
    }}
    }
    ExplSyntaxOff

    begin{document}

    $circs{1}$

    $circs{2}$

    $circs{3}$

    $circs{4}$

    $circs{5}$

    $circs{6}$

    $circs{7}$

    end{document}

            From the TeXbook (page 187, solution on page 326)




            Exercise 19.7

            B. L. User tried typing ‘eqno(*)’ and ‘eqno(**)’,
            and he was pleased to discover that this produced the equation numbers
            ‘(∗)’ and ‘(∗∗)’. [He had been a bit worried that they would come out
            ‘(*)’ and ‘(**)’ instead.] But then a few months later he tried
            eqno(***)’ and got a surprise. What was it?



            When you type an asterisk in math mode, plain TeX considers
            * to be a binary operation. In the cases ‘(*)’ and ‘(**)’, the
            binary operations are converted to type Ord, because they don't appear in
            a binary context; but the middle asterisk in ‘(***)’ remains of type Bin.
            So the result was ‘(∗ ∗ ∗)’. To avoid the extra medium spaces, you can
            type ‘eqno(*{*}*)’; or you can change mathcode`*, if you never use
            * as a binary operation.




            It doesn't matter if we're in an equation number (eqno); the main issue is math mode where the behavior shows. Since circ is a binary operation symbol just like *, you get the same.



            If you want evenly spaced circ symbols you can use



            {circ};{circ};{circ};{circ}


            Even better, define a suitable command:



            documentclass{article}
            usepackage{xparse}

            ExplSyntaxOn
            NewDocumentCommand{circs}{m}
            {
            ensuremath
            {{
            {circ}prg_replicate:nn { #1 - 1 } { ; {circ} }
            }}
            }
            ExplSyntaxOff

            begin{document}

            $circs{1}$

            $circs{2}$

            $circs{3}$

            $circs{4}$

            $circs{5}$

            $circs{6}$

            $circs{7}$

            end{document}
