Floating-point unit
Imagine you have a calculator, like the one you use in math class. This calculator is called a floating-point unit. It's called that because it can handle really big and really small numbers (kind of like floating on water).
Most calculators have two types of numbers: whole numbers (like 1, 2, 3), and decimals (like 0.5, 1.25, 10.123). A floating-point unit can handle both of these types of numbers, PLUS it can handle really big numbers (like a million) and really small numbers (like 0.00001).
The way the calculator handles these big and small numbers is by using something called exponents. This is kind of like how you use powers of 10 in math. For example, if you want to write a really big number, you might write it as 10 to the power of 6 (which is a million). The calculator can handle these exponents and do calculations with them.
So when you use a computer or a phone, there's usually a floating-point unit inside that helps the device do math with really big or really small numbers. It's like having a really smart calculator inside your device!
