Finite decimal

A finite decimal is a type of decimal that has a finite number of numbers after the decimal point. For example, 8.14 is a finite decimal because there are two numbers after the decimal point; 8 and 14. This is different from an infinite decimal which has an unlimited number of numbers after the decimal point. For example, 8.1412543 is an infinite decimal because it has an unlimited number of numbers after the decimal point. Finite decimals are useful in many math problems because they help us understand calculations quickly and easily.
