Real Versus Nominal Value

Bol

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The distinction between real value and nominal value occurs in many fields. From a philosophical viewpoint, nominal value represents an accepted condition which is a goal or an approximation as opposed to the real value, which always is actually present. Often a "nominal" value is a de facto standard rather than a typical or average measurement. When measurement is involved, the real value often has the characteristics of an irrational number. In real-world measuring situations, improving the measurement technique will eventually begin yielding unpredictable least significant digits. For example, a 1 inch long gauge block will measure to be exactly 1 inch long until the measuring techniques reach a certain degree of precision
