[Tex/LaTex] Remove the space between number and % in siunitx

siunitx

I use the siunitx package for unit management. However, i want to remove the space between the number and the percent symbol, i.e. 1% instead of 1 %. Can i redefine the \percent command to achieve this for my complete document so that i do not have to do this by hand and write 1\%.

I have tens of numbers where I'm typing \SI{1}{\percent} and i want to change all these numbers with a single redefinition of "\percent"

You need to redeclare the unit

\documentclass{article}
\usepackage{siunitx}
\DeclareSIUnit[quantity-product = ]\percent{\char`\%}
\begin{document}
\qty{1}{\percent}
\end{document}

The S column is intended for numbers only: it is not the same as using both arguments to \SI. Normally, I would suggest either using two separate columns and remove the inter-column padding uisng @{}:

\documentclass{article}
\usepackage{siunitx}
\begin{document}

\begin{tabular}{lS[table-format=4.4]@{}s}
    One   &    0.1234 & \percent \\
    Two   &    1.234  & \percent \\
    Three &   12.34   & \percent \\
    Four  &  123.4    & \percent \\
    Five  & 1234      & \percent \\
    Six   & 1234.0    & \percent \\
\end{tabular}

\end{document}

or even better adding this information to the header

\documentclass{article}
\usepackage{booktabs,siunitx}
\begin{document}

\begin{tabular}{lS[table-format=4.4]}
  \toprule
    & {Value/\si{\percent}} \\
  \midrule
    One   &    0.1234 \\
    Two   &    1.234  \\
    Three &   12.34   \\
    Four  &  123.4    \\
    Five  & 1234      \\
    Six   & 1234.0    \\
  \bottomrule
\end{tabular}

\end{document}

If you do want the input as given, you need free-standing-units, alter the definition of \percent and fiddle a bit with the alignment settings

\documentclass{article}
\usepackage{siunitx}
\sisetup{free-standing-units}
\DeclareSIUnit[number-unit-product={}]{\percent}{\%}
\begin{document}

\begin{tabular}{lS[table-format=4.4,table-align-text-post=false]}
    One   &    0.1234\percent \\
    Two   &    1.234 \percent \\
    Three &   12.34  \percent \\
    Four  &  123.4   \percent \\
    Five  & 1234     \percent \\
    Six   & 1234.0   \percent \\
\end{tabular}

\end{document}

[Tex/LaTex] How much space between number and unit

At a technical level, detecting whether \SI is used inside display math is already implemented for the detect-display-math option. Thus adding functionality to make a choice of spacing based on whether \SI is used inside display math or elsewhere is quite feasible. Presumably this would require splitting the number-unit-product into two parts, with an alias meaning that the existing option continues to work: as usual, suggestions for names would be welcome. My main concern with adding such an option would be that I've never seen this type of variability in printed material: I'd like to see an 'official' source for such an approach before adding it.
