Floats are acceptable here, since 1.0 == 1 and -1.0 == -1. Nice job using the rarely-used definition of the sign function as the derivative of the absolute value function (with f(0) = 0 explicitly defined)!

| Dec 22, 2016 at 3:15 | comment | added | Cormac | Thank you! I just realised I dont even need to casting at all. I thought that if n == 0 it would evaluate to false so I would have to convert it to an int but it turns out it stays as 0. | |

Welcome to Programming Puzzles & Code Golf! If you replace / with //, you don't need to cast to int.
