A typical wiring for [format currency](https://docs.rual.nl/block-types/finance/currency_format): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [number](https://docs.rual.nl/block-types/number/number_default) feeds the `amount` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `currency` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
