Are all/most modern currencies (mainly used in international business) based on the decimal system.

for开发者_高级运维 example there are 100 pence in a pound, 100 cent in a euro and 100 cent in a dollar.

Is this the same for all currencies major business currencies? (I think it is, im just double checking)

I'd say this is a pretty safe assumption. According to Wikipedia:

Today only two countries in the world use non-decimal currencies. These are Mauritania (1 ouguiya = 5 khoums) and Madagascar (1 ariary = 5 iraimbilanja).
