summary: Parse locale-formatted money text (1.234,56, 1,00,000, accounting parentheses)…
description: 'Parses up to 100 number or money strings such as "1.234,56", "1,00,000", "(1,234.50)", "￥1,000" or "CHF 1''234.50" into canonical decimal strings, for an agent reading amounts from documents, emails or tables. With a BCP 47 locale it applies that locale''s CLDR separators (read from Intl.NumberFormat); without one it lists every valid reading and an ambiguous string such as "1,234" returns unknown with both (1234 and 1.234) instead of a guess. Understands leading and trailing minus, U+2212, accounting parentheses, non-ASCII digit systems and currency symbols or ISO codes (a symbol shared by several currencies, such as ¥ or $, is reported as ambiguous unless the caller names the currency). Does not convert currencies and does not round.
