General ⇒ Thousands separator

[mateovasco]

Hi!

I want to use thousands separator in the numbers. For example, write 10123456.789012, and show 10,123,456.789012

I tried to use numprint package, but it show thousand separator after decimal point. eg. 10,123,456.789,012

Do you know any package???

Thanks!

You can do it with numprint. Load this package. With the settings

Code: Select all

\npthousandsep{,}\npthousandthpartsep{}\npdecimalsign{.}

the command \numprint{1234567890.123456789}, for example, yields 1,234,567,890.123456789 as desired.

I've seen in other thread that you load the spanish language with babel. In this case, the above way of writing decimal numbers is not in accordance with Spanish typography. See the document ortomatem.pdf, by Javier Bezos, about ortotypography in mathematics. I quote two paragraphs from page 17 of this document:

h) El separador decimal es la coma: 3,142.
i) Antes y después de la coma, se pueden separar los dígitos en grupos de tres
con espacios finos: 2,718 281 8. Si se emplean estos espacios finos, se admite su
supresión si la parte entera o la decimal sólo tienen cuatro cifras: 1200, 3,1415.

So, when writing in spanish, I would suggest the following settings for numprint:

Code: Select all

\npthousandsep{\,}\npdecimalsign{,}
