How can I tell LaTex to group by thousands such as a large number like this: 1 000 000 000 instead of 1000000000 Thanks
I don't think you can tell it that, because as far as LaTeX is concerned there is nothing special about numbers. You can do it manually, just type $1\,000\,000\,000$ or $1\;000\;000\;000$ or $1\:000\:000\:000$, depending on your preference. Or use scientific notation ($10^9$), of course :tongue: Examples: $1\,000\,000\,000$ [itex] 1\,000\,000\,000 [/itex] $1\;000\;000\;000$ [itex] 1\;000\;000\;000 [/itex] $1\:000\:000\:000$ [itex] 1\:000\:000\:000 [/itex] $10^9$ [itex] 10^9 [/itex]
This can be accomplished by using the numprint package. Check out http://www.ctan.org/tex-archive/macros/latex/contrib/numprint/ for details.
