operational precision; computational accuracy
Technical term used in computing, mathematics, and engineering to describe the exactness of a calculation or operation.
Operational precision is important in this program.
To increase computational accuracy, more bits are used.
計算精度 is a broader term for calculation accuracy in general, while 演算精度 specifically refers to the precision of an operation or algorithm, often in a computing context.
Compound of 演算 (operation, calculation) and 精度 (precision, accuracy). A straightforward technical term with no obscure historical derivation.
