I am writing a book in the following codes:

The numbers in texts are
and in math environment they are also


After compiling, they are the following way,

enter image description here

My GOAL is to change the numbers' in both texts and math modes to times but not to change to the font of the other texts and math modes. The following is the effect that I want to get. enter image description here NOTE: 1. I don't want to change the font of other non-number texts or non-number math mode. 2. The numbers I talked about here consist of page numbers, enumerating numbers, mathematical numbers and so on.

How can I get these? Any help would be appreciated and welcome!

  • Doesn't the numprint package do this? Jan 1, 2018 at 13:43

    While it is easy to change the font (automatically) in math (see tex.stackexchange.com/a/7510/2388) in text it would need a virtual font to do the same in text. Jan 1, 2018 at 15:43
  • @Ulrike Fischer Thanks although it's not what I want.

  • You're tagged this 'fontspec', but aren't using it. Are you saying this is an option? You would need to compile with Xe/LuaTeX in that case, rather than (pdf)TeX. If not, the tag is erroneous and just confuses things, as you'll likely get answers you don't want.

The SIUNITX package is the way to go.


\usepackage[decimalsymbol=comma,exponent-product = \cdot,per-mode=fraction]{siunitx}
\sisetup{load-configurations = abbreviations}
\sisetup{quotient-mode = fraction} 

This is a number is in the same font as the default font 12351235\\
this is a number as a number is in another font \num{1235123} \\

Resulting in this:
