Overview

## What Precise Special Functions does

This app computes named special functions to a requested number of digits. The set covers the Gamma function, the complete elliptic integrals K and E, the Riemann zeta function, the Gauss hypergeometric function 2F1, and Bessel functions of all four kinds (J, Y, I and K).

Arithmetic runs through mpmath, with precision available up to a thousand decimal places. That range is aimed at work where a double-precision float or a quick inline approximation falls short: physics simulation, number theory and engineering calculation.

Queries are written in ordinary language, for instance asking for the value of J0 at 7.2 to thirty digits. Results are deterministic and can be checked against reference implementations.

### Who it is for

Physicists, mathematicians and engineers who need more digits than a standard float carries.

### What stands out

Precision is settable up to a thousand decimal places, with results reproducible against reference implementations.

Availability

## Where Precise Special Functions is listed

Precise Special Functions is listed in the ChatGPT apps directory only. Assaf Lanir has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
