D specifically supports double (as a 64-bit float), regardless of the
actual hardware. Also, the D way is to make the correct way simple, the
fast way possible. This is clearly in favor of not using float, which
*would* lead to precision loss.

As for double vs real, a 32-bit int neatly fits in any double, making it
good enough. short and byte should convert to float, and I'm not sure
about long/ulong, since real may not have enough bits to accurately
represent it.
