“When writing currency amounts the location of the sign varies by currency. Many currencies, especially in Latin America and the English-speaking world, place it before the amount (e.g., £50.00); many others place it after the amount (e.g., 50.00 S₣); and, before they were abolished, the sign for the Portuguese Escudo and the French Franc were placed in the decimal position (i.e., 50$00 or 12₣34). The standardized European default placement, used in absence of a national standard, is that (€) is placed before the amount. However, many Eurozone countries have sustained or generated alternative conventions.
The decimal separator can also take local countries’ standards. For instance, the United Kingdom often uses a middle dot as the decimal point on price stickers (eg., ’£5·52’), although not in print. A comma (eg. ‘5,00 €’) is a common separator used in other countries.” (Wikipedia)
