Precision
/ˈprɛ-ʒɪ-ʒən/
noun — “how finely a system can distinguish truth from its nearest approximation.”
Precision is the measure of how detailed or exact a numerical representation or computation can be. In computing, it describes the degree to which a value can be represented without losing information due to rounding, truncation, or storage limits. It is closely tied to floating-point systems such as IEEE 754.
