Editing Comma (section)

===In numbers===
{{Main|Decimal separator}}
In representing large numbers, from the right side to the left, English texts usually use commas to separate each group of three digits in front of the decimal.<ref>{{Cite web |title=Common Mathematical Symbols and Terminology |url= https://www.skillsyouneed.com/num/common-symbols.html |access-date=22 August 2020 |website=SkillsYouNeed |archive-date=2 October 2020 |archive-url= https://web.archive.org/web/20201002225233/https://www.skillsyouneed.com/num/common-symbols.html |url-status=live}}</ref> This is almost always done for numbers of six or more digits, and often for four or five digits but not in front of the number itself. However, in much of Europe, Southern Africa and Latin America, [[full stop|period]]s or spaces are used instead; the comma is used as a [[decimal separator]], equivalent to the use in English of the [[decimal separator|decimal point]].<ref>{{Cite web |last=Weisstein |first=Eric W. |title=Decimal Point |url= https://mathworld.wolfram.com/DecimalPoint.html |access-date=22 August 2020 |website=Wolfram MathWorld |archive-date=21 March 2022 |archive-url= https://web.archive.org/web/20220321195047/https://mathworld.wolfram.com/DecimalPoint.html |url-status=live}}</ref> In India, the groups are two digits, except for the rightmost group, which is of three digits. In some styles, the comma may not be used for this purpose at all (e.g. in the [[International System of Units#Unit symbols and the values of quantities|SI writing style]]<ref>{{Cite web |url= http://standards.ieee.org/guides/style/section6.html#695 |title=IEEE Standards Style Manual |date=May 2000 |website=Standards.IEEE.org |publisher=[[Institute of Electrical and Electronics Engineers]] |access-date=9 November 2004 |archive-date=28 October 2004 |archive-url= https://web.archive.org/web/20041028103201/http://standards.ieee.org/guides/style/section6.html#695 |url-status=dead}}</ref>); a space may be used to separate groups of three digits instead.
