# normalizeBigNumbers Reference

This is a reference to the `normalizeBigNumbers` function provided by the `@medusajs/test-utils` package.

This function is available since Medusa [v2.19.0](https://github.com/medusajs/medusa/releases/tag/v2.19.0).

## Summary

`normalizeBigNumbers` recursively converts `BigNumber` instances to plain JavaScript numbers within any object, array, or primitive value. Dates are left intact.

When you retrieve or create orders and carts in tests, numeric fields such as totals are returned as `BigNumber` instances rather than plain numbers. Use `normalizeBigNumbers` when writing Jest assertions against those values so you can compare them to plain-number expectations.

## Example

```ts
import { medusaIntegrationTestRunner, normalizeBigNumbers } from "@medusajs/test-utils"

medusaIntegrationTestRunner({
  testSuite: ({ api }) => {
    it("returns the correct order totals", async () => {
      const { data: { order } } = await api.get("/admin/orders/order_123")

      expect(normalizeBigNumbers(order)).toMatchObject({
        total: 50,
        subtotal: 45,
        tax_total: 5,
      })
    })
  },
})
```

## Parameters

|Name|Type|Description|
|---|---|---|
|\`value\`|\`any\`|The value to normalize. Can be a |

## Returns

Returns the normalized value with all `BigNumber` instances replaced by plain `number` values. The original structure (objects, arrays) is preserved. `Date` instances are returned as-is.
