# Don't repeat exponent in \SIrange

This

``````\SIrange{2e12}{5e12}{\meter}
``````

renders as

I would like to not repeat the exponent, i.e.

``````(2-5)x10^12 m
``````

How can I achieve this?

``````\SIrange[scientific-notation = fixed, range-units = brackets, fixed-exponent = 12]%
Probably in a 'real' case some of these will be set globally (`\sisetup`).
• How can I do this with just a `\numrange` ?
