A while ago, someone e-mailed me about
siunitx and the current choice of fonts for printing. At the moment, the package uses the current maths font for both numbers and units. It was suggested that a better standard setting would be maths font for numbers, text font for units. I’m not going to alter this for version 1, but as I work on version 2 this is something worth considering. In most documents, the difference should not show up. However, I wonder what people think: I can see the logic to the request, but don’t fancy getting lots of complaints either. Comments welcome!
