Dividing Ints won't give a Float?

| I am porting a game. I have been pulling my hair for a while trying to figure out why my code doesn't work in Monkey. Finally, narrowed it down to a wacky problem It looks like this: "test" ends up equalling 0 instead of 0.5 Right now I have to make sure both 1 and 2 are floats. Where this really gets troublesome is when I am not using literals, but a function like: test = DeviceHeight()/45 My game has hundreds of divisions. I would hate to go through and have to change every number to a float. Shouldn't monkey automatically do this? |

| That is correct and it serves a purpose as I have been able to take advantage of it and I am sure many here have also. the thing is that an integer divided by an integer will give you an integer but a float divided by an integer or an integer divided by a float will give you a float. So at least one of the operands have to be a float for the result to be a float. I am not sure if it's explained in the monkey documentation but I believe it is. |

You have to make:test = 1.0/2.0 which is convinient with the behaviour of other languages. You just do an integer division in your example. |

| They don't both have to be floats - just one of them. But it's normal behaviour. Mathematical operations on integers, will give you an integer back. |

| it works by casting also: [monkeycode] local a:float local b:int = 3 local c:int = 4 a = b/Float(c) [/monkeycode] |
