Decimal floating point

Decimal Floating Point (sometimes just called "Floating Point") is a way of representing numbers that uses decimal numbers, like fractions or decimals you've seen in math class. Basically, it uses decimal instead of whole numbers, which allows for more accurate representations of numbers. For example, if you want to represent 0.1 (one tenth), you can't use regular whole numbers - you need to use decimal floating point. This way, you can be sure that you're getting the exact 0.1 instead of a close estimate.
