Ints and Doubles doing division

Question

Short version: Why don\'t I have to coerce 60, and int, into a double, so that I can use division with another double if I DO care about the fractional part?

Answer 1

You can't divide a double by an integer, so the compiler will cast the integer to a double.

So, the expressions (double)durationinseconds / 60 and (double)durationinseconds / 60.0 will result in identical code being created.

I prefer using 60.0 in this case just to make it more visible what the code is actually doing.
