Comment 7 for bug 1090288

I don't think there is a source that will support my claim except that every South African uses the decimal point for currency and numeric values, even on legal documents. There is a government editorial style guide which the Ubuntu team apparently followed here (this document does not differentiate between currency and numeric values):

I am not an expert on this subject and can only find blog posts covering the format of monetary values specifically. However, I have a number of examples where the official government guides are not followed:

Microsoft Windows uses the comma separator for currency and the "." decimal point for numeric values for the South Africa English locale.

The glibc team also uses the "." decimal point for South Africa English locale according to this blog: http://adrianfrith.com/2014/07/20/getting-rid-of-the-decimal-comma-in-ubuntu

Google Docs use the decimal point for both currency and numeric numbers even when selecting Afrikaans (I can't select English South Africa specifically so the next best option is Afrikaans, which is South African).

LibreOffice also uses the "." decimal point for currency and numeric values when selecting English South Africa.

I know the issue is more complex than just me claiming these things but we have to get a discussion going regarding this.
