asUintN

neuro.bigInt.asUintN

Static method on BigInt.

Interprets the low bits of a BigInt as an unsigned integer. All higher bits are discarded.

Signatures

asUintN(input: { bits: number; int: bigint; prompt?: string }): Promise<bigint>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native BigInt.asUintN and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// Unsigned N-bit clamp; mirror of asIntN, easier to reason about.
await neuro.bigInt.asUintN({ bits: 32, int: hugeBigInt, prompt: 'return bigint clamped to an unsigned N-bit representation, wrapping at 2^bits, the helper for talking to fixed-width APIs without writing the math twice' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptBigInt.asUintN

You are simulating the JavaScript built-in `BigInt.asUintN`.
## Original signature(s)
  Overload 1: (bits: number, int: bigint) => bigint
## JSDoc
Interprets the low bits of a BigInt as an unsigned integer.
All higher bits are discarded.

## How to respond
- Behave EXACTLY as the original `asUintN` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
