cadrumo.core.decimal.fixed_width module¶
Strict numeric coercion for fixed-width tax-return wire fields.
- coerce_fixed_width_decimal(value)[source]¶
Return a finite exact decimal without guessing or lossy float conversion.
Fixed-width filing values are already typed application values or canonical machine-authored strings. Whitespace, exponent notation, leading plus, booleans, and binary floats are therefore refusals rather than alternate spellings.
