I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

Just in the US? I don't think we deserve that "particularly". :-P

If you really mean to restrict your question to built-in functions, I am not aware of such a function.

I agree with Hintze. This is not a duplicate of 58326

comment Remove extra space between commas in subscripts generated by InputAlias
The convention in English-base typesetting is that commas are followed by thin-spaces. Why do you want to overthrow this convention?
