# negate

Negate the current state of a RefBigInt.

## Signatures

```ts
export declare const negate: <E, R>(ref: RefBigInt<E, R>) => RefSubject.Computed<bigint, E, R>;
```

## Why

Negate the current state of a RefBigInt. The operation remains attached to the RefSubject's
versioned state boundary.

## Ownership and lifetime

The negate view retains no independent state. An Effect read samples the source once; Fx
observation follows later pushes and its observing Scope owns subscription cleanup.
