Thanks Ali. Is this for backward compatibility with C?
Because, if there is a division, a natural/mathematical (not
programmatic) expectation is to see a a double in the result.
[...]
I have never seen a programming language in which dividing two
integers yields a float or double. Either numbers default to a
floating point type, in which case you begin with floats in the
first place, or division is integer division, yielding an
integer result.

I'm not denying that all the programming languages does it this
way (even if it is a cause of related bugs).
I'm just questioning the reasoning behind why D does it this way
and if it is for compatibility or if there is any other reasoning
behind the decision.
