Stochastic rounding: implementation, error analysis and applications

open access: yesRoyal Society Open Science, 2022
Stochastic rounding (SR) randomly maps a real number x to one of the two nearest values in a finite precision number system. The probability of choosing either of these two numbers is 1 minus their relative distance to x.

A rapidly convergent method for solving third-order polynomials

open access: yesAIP Advances, 2022
We present a rapidly convergent method for solving cubic polynomial equations with real coefficients. The method is based on a power series expansion of a simplified form of Cardano’s formula using Newton’s generalized binomial theorem.
