Round once, on the total.

Some carts were off by a cent. Each line was rounded before tax, so small errors added up.

Rounding rules

Round a monetary amount one time, at the end of the calculation. Rounding in the middle moves the result.

Invoices use half-even rounding. An amount that ends in exactly half a cent goes to the nearest even cent.

See Half-even rounding for the full table.

Run the tax tests

$pnpm vitest run tax-total

The review of the tax path is complete. It has one finding, and a new test fails on it.

What I found

Line rounding: src/checkout/tax-total.ts rounds each line in taxTotal(), then adds the lines. The cart rounds one time, after the sum.

Failing case: three lines of 0.336 give 1.02. The correct tax is 1.01.

Checks run

pnpm vitest run tax-total: 6 passed, 1 failed (the new case).

pnpm tsc --noEmit: passed.

Rounding rules
Round a money value once, at the end of the calculation.
Rounding at every step can move a total by a cent.
Half-even rule
Half-even rule
A value exactly halfway between two cents goes to the even cent.
Over many totals, the rounding errors cancel out.

Dein Chrome-Browser

Notizen aus einem Video
Der Agent entnimmt einem YouTube-Video oder einer Aufnahme die Schritte, die Befehle und die Entscheidungen.
Handy-Benachrichtigungen
Der Agent sendet eine Benachrichtigung an dein Handy, wenn die Arbeit fertig ist, fehlschlägt oder deine Entscheidung braucht.

Erklärvideos, Sprachausgabe und Videonotizen nutzen deinen eigenen Gemini-API-Schlüssel. Das Browser-Tool braucht die Chrome-Erweiterung HB Code Browser Bridge. Handy-Benachrichtigungen brauchen die Einstellung für Benachrichtigungen und ein verbundenes Handy.

Für die tägliche Arbeit gemacht

HB Code führt Claude Code mit dem Claude Agent SDK von Anthropic aus und Codex mit einem eigenen Build des Codex app-server von OpenAI. Jeder Agent behält seinen eigenen Verlauf und seine eigene Anmeldung.

Nachrichten warten auf den Desktop
Wenn das Handy den Desktop nicht erreicht, wartet deine Nachricht auf dem Handy. Sie geht raus, sobald die Verbindung wieder da ist, und ein zweiter Versuch sendet sie nie doppelt.
Eine gespeicherte Unterhaltung fortsetzen
Starte eine Session aus einer Unterhaltung, die der Agent für den Projektordner gespeichert hat. Bei Claude Code gehören auch Unterhaltungen aus dem Terminal dazu. Nach einem Neustart öffnet sich jede Session mit ihrem ganzen Verlauf.
Zehn Farb-Themes
Jedes Theme hat eine helle und eine dunkle Version. Deine Handys nutzen das Theme, das du auf dem Desktop wählst.
Syntaxfarben in Befehlen und Dateien
Befehle haben Shell-Farben, und ein Skript in einem Befehl bekommt die Farben seiner eigenen Sprache. Dateien öffnen sich mit Syntaxfarben und Zeilennummern.
