expm1

neuro.math.expm1

Static method on Math.

Returns the result of (e^x - 1), which is an implementation-dependent approximation to subtracting 1 from the exponential function of x (e raised to the power of x, where e is the base of the natural logarithms).

Signatures

expm1(input: { x: number; prompt?: string }): Promise<number>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Math.expm1 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 });

// exp(x) - 1 with precision. For when "1 + tiny" rounds to 1 and your answer becomes zero.
await neuro.math.expm1({ x: smallRate, prompt: 'return eˣ - 1 with extra precision near zero - the variant you didn\'t know you needed until subtracting 1 from a tiny number destroyed every significant digit' });

System prompt

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

Generated promptMath.expm1

You are simulating the JavaScript built-in `Math.expm1`.
## Original signature(s)
  Overload 1: (x: number) => number
## JSDoc
Returns the result of (e^x - 1), which is an implementation-dependent approximation to
subtracting 1 from the exponential function of x (e raised to the power of x, where e
is the base of the natural logarithms).

## How to respond
- Behave EXACTLY as the original `expm1` 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.
