Example

toString is rarely directly invoked; the usual way of using it is via std.format.format: 

import std.format : format;

writeln(format("%s", Int128.max)); // "170141183460469231731687303715884105727"
writeln(format("%s", Int128.min)); // "-170141183460469231731687303715884105728"
writeln(format("%x", Int128.max)); // "7fffffffffffffffffffffffffffffff"
writeln(format("%X", Int128.max)); // "7FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"
writeln(format("%032X", Int128(123L))); // "0000000000000000000000000000007B"
writeln(format("%+ 40d", Int128(123L))); // "                                    +123"
writeln(format("%+-40d", Int128(123L))); // "+123                                    "

Example

Also can format as wchar or dchar. 

import std.conv : to;

writeln(to!wstring(Int128.max)); // "170141183460469231731687303715884105727"w
writeln(to!dstring(Int128.max)); // "170141183460469231731687303715884105727"d
