| ------- | ------------------------ | -------------------- | ------------------- | -------------------------- | ------------------------- | ------- |
| 0       | 'clone a string'         | '955.81 ± 1.45%'     | '902.00'            | '1095925 ± 0.01%'          | '1108647'                 | 1046239 |
