In D, does a cast from float to int (and vice-versa) actually convert the whole part of the float to an equivalent integer value? Or does the cast merely reinterpret the bits as the other type?

Thanks,
Garett

What is the "equivalent integer value" of a float that is out of the range of the integer it is casted to?

The smallest representable integer. For
long: (0x8000000000000000) -9223372036854775808
int: (0x80000000) -2147483648
etc...

Sadly, it is neither documented nor implemented this way.
