Overview

Perform bounded exact-decimal discount factor with every rate, factor, bound, and profile explicit. Fixed precision, closed input, typed failures, and no ambient financial data apply.

You receive an exact scalar result and explicit profile receipt for finance.discount_factor.

Reliability

DECIMAL_INVALID means a malformed or over-limit decimal; correct it. RATE_INVALID means a rate or rebate mode violates its domain; correct it. FACTOR_INVALID means time, year fraction, or factor is negative or malformed; correct it. PROFILE_INVALID means compounding mode, frequency, time, or exponent is invalid; select a valid profile. ZERO_DENOMINATOR means a discount denominator is zero; change rate or profile. BOUNDS_INVALID means a floor, cap, fee, or rebate is inconsistent; correct its bounds. ROUNDING_INVALID means mode or scale is unsupported; select a published mode and scale. ITEM_LIMIT_EXCEEDED means compound work exceeds 10,000 steps; reduce time or frequency. This guidance applies specifically to finance.discount_factor.

Context footprint

The compact result replaces repeated prompt arithmetic for finance.discount_factor. A successful call costs 1 execution credit.

When to use it

When a rate and year fraction must become the present-value multiplier, not a cash amount.

When you already hold the cash present value, or the rate is still a market quote to fetch.

Input schema

Field	Type	Required	Description
rate	string	Yes	Nominal annual or continuous rate. Required finite plain decimal without exponent notation.
time	string	Yes	Non-negative time in years. Required finite plain decimal without exponent notation.
compoundingProfile	object	Yes	Closed object with `mode`; PERIODIC also requires integer `periodsPerYear` from 1 through 366.

Output schema

Field	Type	Required	Description
discountFactor	string	Yes	Calculated periodic or continuous discount factor. Returned as a normalized plain-decimal string.
compoundingProfile	object	Yes	Closed resolved object with `mode`; PERIODIC also has integer `periodsPerYear`.
