Hi all.

When writing numbers in the SI system the digits of numerical values having more than four digits on either side of the decimal marker are separated into groups of three using a thin, fixed space counting from both the left and right of the decimal marker. Commas are not used to separate digits into groups of three. For example:15 739.012 53

I find that the gap provided by grave (') is too wide for this. Is there a way to make the gap smaller than that provided by grave?

Thanks
