About the Currency Converter
The calculator uses a custom php logic configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
The calculator looks up the live mid-market rate for the selected From and To currencies, then returns the converted amount, the live rate (1 FROM = X TO), and the reverse rate (1 TO = Y FROM).
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: The calculator looks up the live mid-market rate for the selected From and To currencies, then returns the converted amount, the live rate (1 FROM = X TO), and the reverse rate (1 TO = Y FROM). Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
