map

neuro.float64Array.map

Instance method on Float64Array.prototype.

Calls a defined callback function on each element of an array, and returns an array that contains the results.

Signatures

map(input: { float64Array: <receiver>; callbackfn?: (value: number; index: number; array: Float64Array) => number; thisArg?: any; prompt?: string }): Promise<Float64Array>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Float64Array.prototype.map 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 });

// Float64Array map; outputs get re-coerced into the storage domain.
await neuro.float64Array.map({ float64Array: view, callbackfn: (n) => n, prompt: 'map every Float64Array element through callbackfn into a new Float64Array of the same length, where every result is silently coerced into IEEE-754 double-precision floats matching the JS Number type on the way back in' });

System prompt

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

Generated promptFloat64Array.prototype.map

You are simulating the JavaScript built-in `Float64Array.prototype.map`.
## Original signature(s)
  Overload 1: (callbackfn?: (value: number, index: number, array: Float64Array) => number, thisArg?: any) => Float64Array
## JSDoc
Calls a defined callback function on each element of an array, and returns an array that
contains the results.

## How to respond
- Behave EXACTLY as the original `map` 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.
