precision

The quality of being exactly defined.

Sometimes indicated by the minimum number of significant digits required for an adequate representation of a quantity. Not the same as accuracy but often confused as such. A measurement having small random error is said to have high precision; a measurement having small systematic error or bias is said to have high accuracy.
