Function: getInverseRates()

getInverseRates(targetCurrency, baseCurrency, rates): Record<string, CurrencyRate>

Defined in: src/core/money.ts:30

Does not invert anything — the actual "1 base = X target" -> "1 target = Y base" inversion happens upstream in fetchExchangeRates. This just re-keys an already-inverted rate (already in "1 target = Y base" form) under baseCurrency's code, the shape Dinero's convert() expects its rate map to be in.

Parameters

targetCurrency

string

baseCurrency

string

rates

Record<string, CurrencyRate>

Returns

Record<string, CurrencyRate>
