siunitx
-independent PGF solution
The same behaviour of siunitx
’ option group-four-digits
set to false can be achieved in PGF with the /pgf/number format/min exponent for 1000 sep
style.
From the PGF manual, section 66.1 “Changing display styles”, p. 547:
/pgf/number format/min exponent for 1000 sep={<number>}
(no default, initially 0
)
Defines the smallest exponent in scientic notation which is required to draw thousand separators. The exponent is the number of digits minus one, so <number>
= 4 will use thousand separators starting with 1e4 = 10000.
A value of 0
disables this feature (negative values are ignored).
Code
\documentclass{article}
\usepackage{siunitx}
\usepackage{pgf}
\sisetup{
group-digits=true,
group-separator={\,},
}
\pgfkeys{
/pgf/number format/.cd,
set thousands separator={\,},
min exponent for 1000 sep=4,
}
\begin{document}
\begin{tabular}{rll}
siunitx: &\num{9000} &\num{19000} \\
pgf: &\pgfmathprintnumber{9000} &\pgfmathprintnumber{19000} \\
\end{tabular}
\end{document}

siunitx
and PGF
If you want to use siunitx
and PGF’s number printing system consistently together you should check out siunitx
“little” \SendSettingsToPgf
macro.
From the siunitx
manual, section 7.9 “Transferring settings to PGF”, p. 63:
The numerical engine in the pgf
package has settings similar to those in siunitx
. To
enable working with both packages easily, the macro \SendSettingsToPgf
is available.
It will set some commonly-used numerical formatting options in pgf
to the current
values used by siunitx
to make using the two packages together more convenient for
end users. This function can be used at any point after loading both the pgf
and siunitx
packages.
As group-four-digits
is set to false
per default there are no further adjustment needed in your example.
Code
\documentclass{article}
\usepackage{siunitx}
\usepackage{pgf}
\sisetup{
group-digits=true,
group-separator={\,},
% group-four-digits=false,% default setting
}
\SendSettingsToPgf
