Editing Decimal separator (section)

==Current standards==
The 22nd [[General Conference on Weights and Measures]]<ref name=CGPM-22nd-R10/> declared in 2003, "The symbol for the decimal marker shall be either the point on the line or the comma on the line." It further reaffirmed,<ref name=CGPM-22nd-R10> {{cite conference

{{bq|text=Numbers may be divided in groups of three in order to facilitate reading; neither dots nor commas are ever inserted in the spaces between groups}}
That is, "{{nobr|1&thinsp;000&thinsp;000&thinsp;000}}" is preferred over "1,000,000,000" or "1.000.000.000". This use has therefore been recommended by technical organizations, such as the United States's [[National Institute of Standards and Technology]].<ref>{{cite report |first1=Ambler |last1=Thompson |first2=Barry N. |last2=Taylor |date=March 2008 |title=Guide for the Use of the International System of Units (SI) |at=§10.5.3 |publisher=[[National Institute of Standards and Technology]] |url=https://physics.nist.gov/cuu/pdf/sp811.pdf#10.5.3 |access-date=21 January 2022}}</ref>

Past versions of [[ISO 8601]], but not the 2019 revision, also stipulated normative notation based on SI conventions, adding that the comma is preferred over the full stop.<ref>{{cite report |id=ISO/FDIS 8601:2000(E) |title=Data elements and interchange formats — Information interchange |section=§5.3.1.3 – Representation of dates and times |page=15 |date=2000 |publisher=[[International Standards Organisation]] |url=http://xml.coverpages.org/ISO-FDIS-8601.pdf |access-date=8 January 2019}}</ref>

[[ISO 80000-1]] stipulates, "The decimal sign is either a comma or a point on the line." The standard does not stipulate any preference, observing that usage will depend on customary usage in the language concerned, but adds a note that as per ISO/IEC directives, all ISO standards should use the comma as the decimal marker.
