I was taught in the US that "and" in a spelled out number designates the decimal point. So, "ONE HUNDRED ONE" would be 101, while "ONE HUNDRED AND ONE TENTH" would be 100.1 - "ONE HUNDRED AND ONE" would then be considered an incorrect designation. I think this is based on check-writing/banking standards. But I have heard that others learned by other standards both in the US and elsewhere. -A
