 This tool converts the statements from known brokers and exchanges into a format compatible with section 9 from the Portuguese IRS form: [Mod_3_anexo_j](https://info.portaldasfinancas.gov.pt/pt/apoio_contribuinte/modelos_formularios/irs/Documents/Mod_3_anexo_J.pdf)

+## Rounding
+
+All Euro values are rounded to cents (2 decimal places) but internal calculations use the statement values with full precision.
+There are no explicit rules or details about how to round Euro values in Anexo J.
+This application rounds according to `Portaria n.º 1180/2001, art. 2.º, alínea c) e d)` (Ministerial Order / Government Order) examples, which imply we should round to the 2nd decimal place by rounding up (ceiling) or down (floor) depending on whether the third decimal place is ≥ 5 or < 5, respectively.
