Divide two numbers. Part of Lodash 4.x Math (since 4.7.0).
Pass the numbers or collection shown below. Check the return value before you chain another math helper.
Call _.divide. Start with this line.
_.divide(dividend, divisor)| Call | What it does |
|---|---|
_.divide(dividend, divisor) | Primary signature. |
_.divide(a, b) | Run the math helper on numbers or a collection. |
Prefer import divide from "lodash/divide" when you want a smaller bundle.
_.divide(dividend, divisor)| Parameter | Description |
|---|---|
| dividend | Optional. First number in the division |
| divisor | Optional. Second number in the division |
| Return Value | Description |
|---|---|
| * | Quotient, or short-circuit / default 1 |
Divide two numbers and get a float quotient.
_.divide(6, 4);
// → 1.56, divisor 4./ after numeric coercion.1.5 — same as the official docs._. math helpers.undefined → 1The default for divide/multiply is the multiplicative identity.
_.divide();
// → 1
_.divide(undefined, undefined);
// → 1createMathOperation(…, 1) sets the empty default.1 is the multiplicative identity (like 0 for add).NaN._.add() returns 0 for the same empty case.The defined value is returned without dividing.
[
_.divide(6, undefined),
_.divide(undefined, 4)
];
// → [6, 4]/. Division never runs in that branch.null is coerced (often to 0) — different from omitting an arg.Same IEEE-754 result as native JavaScript — no exception.
[
_.divide(10, 0),
_.divide(-10, 0),
_.divide(0, 0)
];
// → [Infinity, -Infinity, NaN]10 / 0 → Infinity.-10 / 0 → -Infinity.0 / 0 → NaN.divisor === 0 yourself if you need an error or fallback.divide vs multiplySame factory family; opposite operations.
[
_.divide(6, 4),
_.multiply(6, 4)
];
// → [1.5, 24]a / b.a * b.1 when both args are undefined._.divide is a Lodash 4.x Math helper (since 4.7.0). It uses native division after Lodash’s math-operation coercion.
Available in [email protected] full builds and the lodash/divide modular import. Works in evergreen browsers and Node / Bun / Deno when Lodash is installed.
Bottom line: Safe for production once Lodash is on the page or in your bundle. Prefer import divide from "lodash/divide" for smaller builds.
Round a number down toward −Infinity with optional precision.
