What Precise Special Functions does in ChatGPT
The Precise Special Functions plugin computes very precise values of specialized math functions from ChatGPT. It covers Bessel functions (J, Y, I and K), the Riemann zeta function, the Gauss hypergeometric function, complete elliptic integrals K and E, and the Gamma function.
Results come from mpmath, a library for arbitrary-precision arithmetic, and can run to 1,000 decimal digits. That matters when a normal floating-point number or a quick code approximation is not precise enough, as in physics simulations, number theory or engineering work.
Every result is deterministic, meaning the same input always gives the same output, and can be checked against reference implementations. You ask in plain words, such as the value of J zero at 7.2 to 30 digits, and get the number back.
