This program compiles and runs with no errors, Don and Aldo Nunez think there
are some inconcistancies here:

void main() {
    static assert((cast(ushort)(-1.0L)) == 0xFFFF);
    static assert((cast(uint)(-1.0)) == 0);
    static assert((cast(uint)(-1.0L)) == 0);
    static assert((cast(ulong)(-1.0L)) == 0xbff0000000000000UL);

    assert((cast(ushort)(-1.0L)) == 0xFFFF);
    assert((cast(uint)(-1.0)) == 0);
    assert((cast(uint)(-1.0L)) == 0);
    assert((cast(ulong)(-1.0L)) == 0xbff0000000000000UL);
}


Don>The cast(uint) case is clearly a bug.<
