siunitx
I want to force siunitx to display numbers in standard form (e.g., 1.23 x 103) unless the number is between 0 and 10. How can I do this?
Thanks for any help.
Edit: I'm actually formatting numbers from a csv file using csvsimple, so I'm using \num{\myvalue}, where I don't know what \myvalue will be.
You could let siunitx take care of the of the alignment and of formatting the numbers: Since version 2.4, siunitx can format numbers to engineering notation.
\documentclass{article}
\usepackage{pgfplotstable}
\usepackage{siunitx}
\begin{document}
\pgfplotstableread{
A B C
1.1 12 1300000
21.1 200000 214300000
}\mytable
\pgfplotstabletypeset[columns={A, B, C},
columns/A/.style={
column type={S[table-format=2.1]},
string type,
postproc cell content/.append style={
/pgfplots/table/@cell content/.add={}{\,s}
}
},
columns/B/.style={
column type={S[round-mode=figures, round-precision=3, scientific-notation=engineering, table-format=3e1]},
string type,
postproc cell content/.append style={
/pgfplots/table/@cell content/.add={}{\,\si{\per\second}}
}
},
columns/C/.style={
column type={S[round-mode=figures, round-precision=3, scientific-notation=engineering, table-format=5.2e1]},
string type,
postproc cell content/.append style={
/pgfplots/table/@cell content/.add={}{\,s}
}
},
]\mytable
\end{document}
May I suggest a slight alteration to your table setup? Instead of repeating the unit symbol with each value, I would put it into the header. Here's one example of how that can be accomplished. I've also used the booktabs package to make the table a bit easier to grasp:
\documentclass{article}
\usepackage{pgfplotstable}
\usepackage{siunitx}
\usepackage{booktabs}
\begin{document}
\pgfplotstableread{
A B C
1.1 12 1300000
21.1 200000 214300000
}\mytable
\pgfplotstabletypeset[columns={A, B, C},
columns/A/.style={
column type={S[table-format=2.1]},
string type
},
columns/B/.style={
column type={S[round-mode=figures, round-precision=3, scientific-notation=engineering, table-format=3e1]},
string type
},
columns/C/.style={
column type={S[round-mode=figures, round-precision=3, scientific-notation=engineering, table-format=3.2e1]},
string type
},
every head row/.style={
before row={\toprule},
after row={\si{\second} & \si{\per\second} & \si{\second}\\ \midrule}
},
every last row/.style={after row=\bottomrule}
]\mytable
\end{document}
To stop siunitx from trying to parse the column names, issue the key multicolumn names. This will wrap the cells in the head row in \multicolumn{1}{c}{<column name>}, which protects them.
\documentclass{article}
\usepackage{pgfplotstable}
\usepackage{siunitx}
\usepackage{booktabs}
\begin{document}
\pgfplotstableread{
d
7000000
}\loadedtable
\pgfplotstabletypeset[
multicolumn names,
columns/d/.style={
column name=$\gamma \times \epsilon$,
column type={
S[
round-mode=places,
round-precision=1,
scientific-notation=engineering,
table-format=1.1e1,
exponent-product = \cdot
]
},
string type
}
]\loadedtable
\end{document}
I would use one of these codes:
\documentclass{article}
\usepackage{geometry} \usepackage{siunitx}
\sisetup{range-phrase=--, fixed-exponent=2, scientific-notation = fixed, range-units =single, table-number-alignment =center, table-figures-exponent=1}
\begin{document}
\begin{table}
\centering
\begin{tabular}{l|S}
Ref & {Value} \\
1 & 1.0e2 \\
2 & 1.5e2 \\
3 & \SIrange{1.0e2}{2.0e2}{} \\
4 & 2.0e2
\end{tabular}
\qquad
\begin{tabular}{l|c}
Ref & {Value} \\
1 & \num{1.0e2} \\
2 & \num{1.5e2} \\
3 & {\SIrange{1.0e2}{2.0e2}{}} \\
4 & \num{2.0e2}
\end{tabular}
\end{table}
\end{document}

Use
\sisetup{scientific-notation = true}. See page 25 of thesiunitxmanual for more options.
