Overview

Round one monetary amount under an explicit or currency-derived scale. The skill uses exact decimal arithmetic, reports the resolved policy, rejects unknown properties, and never fetches a rate or infers accounting policy.

Money arithmetic needs explicit currency, scale, tolerance, and rounding semantics; an LLM cannot guarantee those constraints or reproduce residuals.

Reliability

STRICT and stateless. AMOUNT_INVALID means a malformed or over-limit decimal; fix it. CURRENCY_UNKNOWN means the code is outside the documented allowlist; send a supported code. CURRENCY_MISMATCH is triggered when one sum contains different currency codes; retry only after converting first or splitting the rows by currency. TOLERANCE_INVALID means a negative or unsupported tolerance; correct its type and value. ROUNDING_INVALID means mode or scale is unsupported; choose a documented value. ITEM_LIMIT_EXCEEDED means more than 10,000 rows; split them.

Context footprint

One call returns normalized money strings and the resolved policy. A successful call costs 1 execution credit.

When to use it

When one monetary amount must be rounded to a currency's minor units or an override scale.

When you only need an unrounded total, or the ISO currency code is still unknown.

Input schema

Field	Type	Required	Description
amount	string	Yes	Required plain monetary decimal under the W00 ceilings.
currency	string	Yes	Required supported ISO 4217 code; sets the default scale.
scale	integer	No	Optional 0 to 12; omitted uses the currency minor units.
roundingMode	string	No	Optional supported RoundingPolicy mode; omitted means HALF_UP.

Output schema

Field	Type	Required	Description
amount	string	Yes	Rounded amount at exactly the resolved scale.
currency	string	Yes	Normalized ISO 4217 code.
roundingDelta	string	Yes	rounded amount minus input amount.
policy	object	Yes	Resolved object with string mode, integer scale from 0 to 12, and string point equal to final.
currencyProfile	string	Yes	Versioned currency metadata profile used for the default scale.
