# RefBigInt.isGreaterThan

Check if the current state of a RefBigInt is greater than a BigInt.

## Signatures

```ts
export declare const isGreaterThan: {
    (that: bigint): <E, R>(ref: RefBigInt<E, R>) => RefSubject.Computed<boolean, E, R>;
    <E, R>(ref: RefBigInt<E, R>, that: bigint): RefSubject.Computed<boolean, E, R>;
};
```

## Why

Check if the current state of a RefBigInt is greater than a BigInt. The operation remains
attached to the RefSubject's versioned state boundary.

## Ownership and lifetime

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