Float is a datatype. It's a number with decimals like 0,123456. In Swift you can declare a variable of type float with a value of 0,12 for example as var nameOfVariable: Float = 0,12 in Objective C as: float nameOfVariable = 0,12 or when you want a property @property(nonatomic,assign) float nameOfVariable In the video of C fundamentals it should be explained somewhere.
