The language has cent and ucent reserved for the use of 128-bit signed and
unsigned integers, but they aren't actually implemented yet, and I don't
know what it would take for Walter to decide that it makes sense to
implement them (maybe 128-bit x86 CPUs?). So, the language was designed with
the idea that they could be added, but there are not currently any plans to
add them AFAIK.
Phobos has std.bigint, which supports arbitrarily large integers, but there
is no standard 128-bit integer solution at present. There may be such a
solution on code.dlang.org, but I'm not aware of one.
