= Spacing=
TeX handles math spacing by breaking a formula into parts, and assigning each of those parts a role such as 'Ord' (a variable or number) or 'Rel' (equality, larger than, et cetera). For each combination of roles, it then looks up the spacing appropriate between them in a table. These are the roles:
{| class=wikitable
| Ord || e.g. ''4'' or ''a'' or ''x<sup>2</sup>''
|-
| Op || Unary operators such as ''sin'' or ''ln''.
|-
| Bin || Binary operators such as '+'
|-
| Rel || Relationships such as '=' or '>' or '\implies'
|-
| Open || open brackets of any kind
|-
| Close || closing brackets of any kind
|-
| Punct || Punctuation: digit separators like '.' or ','.
|-
| Inner || Fractions are inner. What else is inner?
|-
|}
To set up e.g. the spacing between ordinal items, do as follows (since dec 2012):
\startsetups math:morespacing
\ordordspacing\textstyle 1mu plus .5mu minus .25mu\relax
\stopsetups
\setupmathematics
[setups=math:morespacing]
