javascript float或double来处理货币/货币值

Question

Which type to use (float or double) for handling currency/money? At the moment I am using float for handling currency/money. I searched through the net, but found nothing. I know this is a question that includes debate which is not allowed, but I need some explanation for me to decide.

Thanks

Answer 1

There is only one type of number in javascript . So you don't really have a choice.

Answer 2

All numbers in JavaScript are 64-bit floating point numbers, ie double.

See the following links for more information:

You don't have a choice in regard to the way your numbers are stored.
