The JavaScript `Math.trunc()`

method *only* works on the number primitive values, and *not* on the bigint primitive values:

```
// TypeError: Cannot convert a BigInt value to a number
Math.trunc(2n);
```

In fact, bigint values have *no* need for a "truncate" (or "trunc") method because:

- Bigint values are integers, and as such
*do not*have a fraction part to "truncate" (or remove); - Operations involving bigint values that produce a fractional result (such as division) are automatically truncated, and
*do not*return any fractional digits.

For example:

// ES10+ const truncated = 10n / 4n; console.log(truncated); // 2n (and not 2.5n)

The "`n`

" at the end of a number merely suggests that the number is a bigint primitive.
