Description Berni44 2021-03-28 08:45:23 UTC 
All asserts fail, while with %d they work.

unittest
{
    assert(format!"%+b"(15) == "+1111");
    assert(format!"%+o"(15) == "+17");
    assert(format!"%+x"(15) == "+f");
    assert(format!"%+X"(15) == "+F");

    assert(format!"% b"(15) == " 1111");
    assert(format!"% o"(15) == " 17");
    assert(format!"% x"(15) == " f");
    assert(format!"% X"(15) == " F");
}
Comment 1 Berni44 2021-04-10 06:12:37 UTC 
Meanwhile I think, this is intentional: These format characters give the image of the bit pattern, which means, there is no sign. So closing this as invalid.
