# mod

Get the remainder of dividing the current state of a RefBigInt by a BigInt.

## Signatures

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

## Why

Get the remainder of dividing the current state of a RefBigInt by a BigInt. The operation
remains attached to the RefSubject's versioned state boundary.

## Ownership and lifetime

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