denom

Denom is a term with two common uses in English: mathematics and currency. In mathematics, denom is short for denominator, the bottom part of a fraction. In a fraction a/b, the denominator is b and indicates into how many equal parts the whole is divided. The denominator must be nonzero. Denominators may be integers or algebraic expressions; when adding or subtracting fractions, one often converts to a common denominator (least common denominator). Denominators also appear in rational expressions and equations, where restrictions exclude values that would make the denominator zero.

In currency and finance, denomination refers to the nominal value of a coin or banknote. The term is used to describe the different monetary values in circulation, such as denominations of 1, 5, 10, and 20 units of a currency. Denominations influence cash handling, pricing, and monetary policy. The word denom is sometimes used informally to refer to a denomination value or to the denomination field in a financial database or software system. In numismatics and commerce, denomination distinguishes coins and notes by their face value rather than their metal content or design.
