Description:
The locale for South Africa inside Calc is wrong. Whether Decimal Separator Key is checked to be the same as locale makes no difference.

Calc doesn't treat numbers with . that conform to the system formatting as numbers because it is expecting a comma as a decimal separator. South Africa last used the comma as a decimal separator over 25 years ago.

There isn't an easy way to configure it to be correct throughout the spreadsheet. 

Steps to Reproduce:
1.System regional settings are set to South Africa (i.e. currency is Rands, decimal separator is . and thousands grouping is space)
2. Language settings in Libre Office are South African English
3. Open a new spreadsheet in Calc
4. Numbers are displayed with , as decimal separator and are required to be entered with , as a decimal separator
5. When I copy numbers from other applications with the decimal as . Calc treats it as text
6. If you try to multiple a number with a . by 2 as decimal separator it gives a value error. If you try to multiple a number with a , by 2 as decimal separator it gives a number answer with , as separator

Actual Results:
The locale for South Africa inside Calc is wrong. Whether Decimal Separator Key is checked to be the same as locale makes no difference.

Calc doesn't treat numbers with . that conform to the system formatting as numbers because it is expecting a comma as a decimal separator. South Africa last used the comma as a decimal separator over 25 years ago.

Expected Results:
Numbers and dates in Calc should conform to what is specified as system-wide settings. At the very least, the locale settings for South Africa in Libre Office should be set to have . instead of , as decimal separator.
