Functions

func StraightRates 

func StraightRates(intRates []*InterestRate) map[time.Time]float64

StraightRates returns a map which maps a rate to each day in the time period. This includes (artificial) rate values for non-business days. intRates must be sorted by date in increasing order.

func WeightedRates 

func WeightedRates(intRates []*InterestRate, dateInit, dateFinal time.Time, holidays []time.Time, startIndex int) (map[time.Time]float64, int)

WeightedRates returns a map which maps a rate to each business day in the time period given by @dateInit and @dateFinal. Rates are weighted by the rate factor. intRates must be sorted by date in increasing order.
