Decimal numbers by default are doubles, but by adding f to the end of the decimal number you tell the program that the decimal number is a float instead. Double and float are both decimal numbers, but they have a difference: Doubles can have 15 decimal places. Floats can have 7 decimal places. 4.2 would be a double 4.2f would be a float
