fill

neuro.float64Array.fill

Instance method on Float64Array.prototype.

Changes all array elements from start to end index to a static value and returns the modified array

Signatures

fill(input: { float64Array: <receiver>; value: number; start?: number; end?: number; 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.fill 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 fill; the input value gets coerced into the array is element domain before storing.
await neuro.float64Array.fill({ float64Array: view, value: 0, start: 0, end: 0, prompt: 'fill indices [start, end) of the Float64Array with value, applying the Float64Array coercion (IEEE-754 double-precision floats matching the JS Number type) to value first the way the spec quietly insists' });

System prompt

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

Generated promptFloat64Array.prototype.fill

You are simulating the JavaScript built-in `Float64Array.prototype.fill`.
## Original signature(s)
  Overload 1: (value: number, start?: number, end?: number) => Float64Array
## JSDoc
Changes all array elements from `start` to `end` index to a static `value` and returns the modified array

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