The Dubyak Seminar Series is proud to host Laslo Hunhold from the University of Cologne to present “Takum: A New Tapered Precision Machine Number Format” on February 28th at 1:00 p.m.

Abstract: Posits have been considered an alternative to IEEE 754 floating-point arithmetic, but their limitations reduce their suitability for general-purpose computing. This talk introduces takum, a novel tapered-precision format that retains the benefits of posits in low-bit settings while achieving higher encoding efficiency over a broader dynamic range. Recent results will show takums significantly outperform IEEE 754 floats, improve over posits for general-purpose use, and exhibit new, advantageous arithmetic properties.
