Improve siunitx support

[jgm]

Here are some examples from the documentation:

\num{12345,67890}

\num{1+-2i}

\num{.3e45}

\num{1.654 x 2.34 x 3.430}

\si{kg.m.s^{-1}}

\si{\kilogram\metre\per\second}

\si[per-mode=symbol]{\kilogram\metre\per\second}

\si[per-mode=symbol]{\kilogram\metre\per\ampere\per\second}


\numlist{10;20;30}

\SIlist{0.13;0.67;0.80}{\milli\metre}

\numrange{10}{20}

\SIrange{0.13}{0.67}{\milli\metre}

\ang{10}

\ang{1;2;3}

\ang{;;1}

\ang{+10;;}

\ang{-0;1;}

\si{kg.m/s^2}

\si{g_{polymer}~mol_{cat}.s^{-1}}

\si{\kilo\gram\metre\per\square\second}

\si{\gram\per\cubic\centi\metre}

\si{\square\volt\cubic\lumen\per\farad}

\si{\metre\squared\per\gray\cubic\lux}

\si{\henry\second}

They render as follows:

Still need numlist and some spacing issues.

And \ampere

[jgm]

need to add tests and fix spacing.

Current renderings of the above examples:

To fix

• \num{1+-2i} should have plus-or-minus symbol instead of +-
• \si{\kilogram\metre\per\second} (without per-mode=symbol) should use exponent -1 instead of /
• \num{.3e45} should have a leading 0.
• \si[per-mode=symbol]{\kilogram\metre\per\ampere\per\second} should be kgm/(A s) not kgm/A/s
• \SIlist{0.13;0.67;0.80}{\milli\metre} doesn't render at all!
• \ang{+10;;} should not have the + sign
• \si{\kilo\gram\metre\per\square\second} should render with negative exponent instead of /
• \si{\gram\per\cubic\centi\metre} (a) should use negative exponent instead of slash, (b) splits up "cm" and puts the exponent on c

Some others have discrepancies which will be fixed if these are.

Hi.
Why is this issue closed when this feature is not implemented?

• \si[per-mode=symbol]{\kilogram\metre\per\ampere\per\second} should be kgm/(A s) not kgm/A/s

[jgm]

Maybe just an oversight? Probably best to open a new issue for this.

[jiucenglou]

Could this be made to work for tex->docx or md->docx ?

[krtko1]

probably add new issue for it.
