| Abstract: |
| This paper proposes rough number notion based on rough sets，and crests its operational laws．It illustrates its application in the practice．Finally，it describes theoreti-cal value of rough approximate operator λ in rough logic． |
| Key words: Rough sets,Rough number,Rough logic,approximate operator． |
