Classes

Act365

The Actual/365 day count convention which specifies that the number of days in the Calculation Period or Compounding Period in respect of which payment is being made is divided by 365.

ActISDA

The Actual/ISDA day count convention which follows the ISDA understanding of the actual/actual convention included in the 1991 ISDA Definitions.

Calculator

The calculator class provides the entry point for solving unknown values and/or unknown interest rates implicit in a cash flow series.

CashFlowAdvance

Represents the movement of money, specifically the cash out flows of a lender, for example the amounts advanced under a loan or leasing arrangement.

CashFlowCharge

Represents the movement of money, specifically non-interest bearing cash in-flows to the lender, for example cash-based charges or fees. The value of these cash flows must be specified i.e. they cannot be null or unknown.

CashFlowPayment

Represents the movement of money, specifically interest bearing cash in-flows to the lender, for example loan repayments or lease rentals.

EU200848EC

The European Union Directive 2008/48/EC (Consumer Credit Directive) day count convention, used exclusively within EU member states in the computation of the Annual Percentage Rate of Charge (APRC) for consumer credit agreements.

EU30360

The 30/360 (EU) day count convention which specifies that the number of days in the Calculation or Compounding Period in respect of which payment is being made is divided by 360, calculated on a formula basis as follows:

Profile

A container for a series of cash in-flows and out-flows.

SeriesAdvance

A series of one or more advances paid out by a lender. This could comprise a series of amounts loaned to a borrower, the lessor's net investment in a lease agreement, etc.

SeriesCharge

A series of one or more charges or fees received by a lender. These are non-financing cash flows which are excluded from the computation of unknown advance or payment cash flow values, but are included under certain circumstances in other calculations for instance the computation of implicit interest rates such as Annual Percantage Rates (APRs), as documented elsewhere.

SeriesPayment

A series of one or more loan payments, lease rentals, etc., received by a lender.

US30360

The 30/360 (US) day count convention which specifies that the number of days in the Calculation Period or Compounding Period in respect of which payment is being made is divided by 360, calculated on a formula basis as follows:

Enums

DayCountOrigin

The day count origin demarcates the start date used in determining the number of days in a time period. Time periods are computed with reference to:

EUTimePeriod

Frequency

Frequency demarcates the compounding period between two cash flows. Options are:

Mode

Mode determines whether a cash flow occurs at the start or end of the compounding period demarcated by cash flow frequency. The options are:

Functions

gaussRound(double num, [int precision = 0]) → double

Perform gaussian rounding, also known as “bankers” rounding, convergent rounding, Dutch rounding, or odd–even rounding. This is a method of rounding without statistical bias; regular rounding has a native upwards bias. Gaussian rounding avoids this by rounding to the nearest even number.

Exceptions / Errors

UnsolvableException

Exception thrown when the unknown cash flow values or interest rate implicit in a cash flow series cannot be solved within a finite number of iterations.
