What does the float do in java like declare blablabla as float?
float and double are types of numbers that accept decimals. Consider them as numbers in scientific notation. double allows a larger range of numbers than float, and more significant digits. Usually you would use double, unless you have some special situation, like a large array of numbers, and you decide the extra precision is not necessary.
