 * All operations on a Money return another Money with the same context. The available contexts are:
 *
 * - DefaultContext handles monies with the default scale for the currency.
 * - CashContext is similar to DefaultContext, but supports a cash rounding step.
 * - CustomContext handles monies with a custom scale and optionally step.
 * - AutoContext automatically adjusts the scale of the money to the minimum required.
