Different countries officially designate different symbols to use specific symbols to separate thousands.

In the United States, this symbol is a comma (,). In Germany, it is a period (.). Thus one thousand and twenty-five is displayed as 1,025 in the United States and 1.025 in Germany. In Sweden, the thousands separator is a space.

In Precoro we support only comma separator now.
