Floating point
In mathematics and science, very large and very small numbers are often made simpler and multiplied to a power of ten to make them easier to understand. For example, it can be much easier to read 1.2 trillion as  than 1,200,000,000,000. This can also be used with negative powers of ten to make small numbers, meaning you can represent 0.000001  as . This process is called scientific notation.
