Math & Science ⇒ Number List and its final Separator

[muchalh]

First and foremost, thanks to Joseph Wright for developing and maintaining siunitx package.

I have a problem with \SIlist macro. The desired result:

3.23 (dd, J = 3.9, 0.9 Hz, 1H).

and I'm using this code:

Code: Select all

\num{3.23} (dd, \emph{J} = 3.9, \SI{0.9}{\Hz}, 1H).

It works fine but I thought I could use \SIlist macro and eventually automate things a bit:

Code: Select all

\num{3.23} (dd, \emph{J} = \SIlist[list-units=single,list-final-separator = {, }]{3.9;0.9}{\Hz}, 1H)

I get the following result (with "and" instead of a comma):

3.23 (dd, J = 3.9 and 0.9 Hz, 1H)

A list of three or more values works OK:

Code: Select all

\num{3.23} (ddd, \emph{J} = \SIlist[list-units=single,list-final-separator = {, }]{3.9;0.9;0.1}{\Hz}, 1H)

3.23 (dd, J = 3.9, 0.9, 0.1 Hz, 1H)

Any ideas? Thank you.

Edit:
Problem already solved. That was quick, Joseph. Thank you.
You need to use list-pair-separator={, } when two numbers are listed.
