Here is a reduced code:
import std.stdio;
enum Type { Int, Float }
auto foo(Type t)
{
final switch (t) {
case Type.Int:
return 42;
case Type.Float:
return 1.5;
}
}
void main()
{
writeln(foo(Type.Int));
writeln(foo(Type.Float));
}
The return type of foo() is double. (It's float in your code but it
doesn't matter.)
I think this is a bug. I guess that 'return 42' is still placing an int
onto the program stack instead of a float. A workarounds are returning
to!float(this._num.ivalue).
But I think this is a compiler bug.
