Definitions

In plain terms

US dollars use cents in these examples, but other currencies need different scales or special handling.

Technical

An integer wire amount must be paired with currency and exponent; D30 USD amount 12345 means USD 123.45.

Scope

ISO scale does not decide product rounding, intermediate precision or cash-payment increments.

Examples

  • A synthetic USD 12.34 amount is stored as 1234 minor units without a floating-point conversion.

Common misconceptions

  • Every currency cannot safely be divided by 100.
