pub const UPPER_BOUND: i64 = _; // 999_999_999_999_999_999i64Expand description
| Upper bound for mantissa. | | 10^18-1 is the largest arbitrary decimal that | will fit in a signed 64-bit integer. | | Larger integers cannot consist of arbitrary | combinations of 0-9: | | 999999999999999999 1^18-1 | 9223372036854775807 (1<<63)-1 (max int64_t) | 9999999999999999999 1^19-1 (would overflow)
