  "message": "Fix `Int64.toRadixStringUnsigned` extra leading digits (#926)\n\nCurrently `Int64.toRadixStringUnsigned` adds an extra \u00270\u0027 when the result is\nsingle digit, e.g. \u002702\u0027 instead of \u00272\u0027.\n\nTo be able to use the standard library `toRadixString`, we split the number\ninto two halves, then calculate the lowest digit and the rest of the digits\nseparately. With the lowest digit removed, the rest of the digits can be passed\nas a positive integer to `toRadixString`. The resulting strings are then\nconcatenated to get the final result.\n\nThe problem occurs when the number can be printed as a single digit. In this\ncase the rest of the number is printed as \u00270\u0027, giving us e.g. \u002702\u0027 instead of\n\u00272\u0027.\n\nTo fix, we return early by calling the standard library `toRadixString` when\nthe number is positive.\n\nThis works because\n\n- The problem is only when printing single digits (as the lowest digit and the\n  rest are printed separately, and the problem is when the \"rest\" part is 0)\n\n- Single-digit numbers need to have high 32-bits as zero (otherwise they\u0027ll be\n  negative and printed as many digits, or positive but larger than single\n  digit).\n\n- When the high 32-bits are all zero, the number is positive, and can be\n  converted to string directly with the standard library signed\n  `toRadixString`.",
