RangeError: BigInt division by zero

The JavaScript exception "BigInt division by zero" occurs when a BigInt is divided by 0n.

In this article

Message

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

Error type

RangeError.

What went wrong?

The divisor of a division or remainder operator is 0n. In 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
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
const a = 1n; const b = 0n; const quotient = b === 0n ? undefined : a / b;
