Division

Question

Hi there.
I get the point and I quit appreciate the concept.
But having the division operator choice returning an integer is odd, isn't it? In most cases an integer divided by another integer will result in a float or double. Will there be an error or some sort of round value?
Thanks.

If you divide an integer by another, it will give an integer. But if you divide a float by an integer, it will give a float. Modern languages saved the old syntax, for example from Pascal, when an integer could be divided only by "div" - division and "mod" - module and the / division could be used only by "real" type, or float. So to be simpler, in modern langauges the / division was made global, and only changes in the calculus and logical use. If you want a float from a division of 2 int just make this: int x = (float)12 for a quick conversion. But in most cases you'll want an int.
