Floats are similar to integers, but they can also include decimal fractions. Float means that the numbers always have a decimal part separated by a dot. The number of decimals is also called precision, e.g.
- 5.8656345
- -332.8463463463753646
Normally you do not need very high precisions for your calculations and two or three decimals will be enough in 99% of all cases. Floats and integers can be used together and the result is always a floating number:
