Multiplication on a common microcontroller is easy. But division is much more difficult. Even with hardware assistance, a 32-bit division on a modern 64-bit x86 CPU can run between 9 and 15 cycles.

Abstract: This research study presents the design of a floating-point ALU which calculates shortest distance between two floating point numbers. Such a unit is used extensively in cluster algorithm.

Add a description, image, and links to the floating-point-numbers topic page so that developers can more easily learn about it.

AI is all about data, and the representation of the data matters strongly. But after focusing primarily on 8-bit integers and 32‑bit floating-point numbers, the industry is now looking at new formats.

An unfortunate reality of trying to represent continuous real numbers in a fixed space (e.g. with a limited number of bits) is that this comes with an inevitable loss of both precision and accuracy.

Interest in sun shields, once a fringe idea, has grown. Now, a team of scientists says it could launch a prototype within a few years. By Cara Buckley Cara Buckley reported from Earth, specifically ...

Abstract: We introduce a number system called "jumping-floating-point" (JFP), which has both the characteristics of the fixed-point and the floating-point number systems. We also introduce a DSP ...
