RangeError: BigInt division by zero

The JavaScript exception "BigInt division by zero" occurs when a {{jsxref("BigInt")}} is divided by 0n.

Message#

RangeError: Division by zero (V8-based)
RangeError: BigInt division by zero (Firefox)
RangeError: 0 is an invalid divisor value. (Safari)

Error type#

{{jsxref("RangeError")}}.

What went wrong?#

The divisor of a division or remainder operator is 0n. In {{jsxref("Number")}} arithmetic, this produces Infinity, but there's no "infinity value" in BigInts, so an error is issued. Check if the divisor is 0n before doing the division.

Examples#

Division by 0n#

```js example-bad const a = 1n; const b = 0n; const quotient = a / b; // RangeError: BigInt division by zero

Instead, check if the divisor is `0n` first, and either issue an error with a better message, or fallback to a different value, like `Infinity` or `undefined`.

```js example-good
const a = 1n;
const b = 0n;
const quotient = b === 0n ? undefined : a / b;
