Implementation of float-float operators on graphics hardware

The Graphic Processing Unit (GPU) has evolved into a powerful and flexible processor. The latest graphic processors provide fully programmable vertex and pixel processing units that support vector operations up to single floating-point precision. This computational power is now being used for general-purpose computations. However, some applications require higher precision than single precision...

Float-polishing process and analysis of float-polished quartz.

A fluid-mechanical model is developed for the float-polishing process. In this model laminar flow between the sample and the lap results in pressure gradients at the grooves that support the sample on a fluid layer. The laminar fluid motion also produces supersmooth, damage-free surfaces. Quartz substrates for applications in high-stress environments were float polished, and their surfaces were...

Float on a Note ∗

From 1863-1914, banks in the U.S. could issue notes subject to full collateral, a per-period tax on outstanding notes, redemption of notes on demand, and a clearing fee per issued note cleared through the Treasury. The system failed to satisfy a purported arbitrage condition; i.e., the yield on collateral exceeded the tax rate plus the product of the clearing fee and the average clearing rate o...

Twin-float arithmetic

We present a heuristically certified form of floating-point arithmetic. As prerequisite we need floating-point arithmetic where the user can set the precision. Our work is developed from the idea of paired floats expounded by Traverso and Zanoni [2]. Twin-float arithmetic is suitable for use only where the input data are exact (or can be obtained to high enough precision). The arithmetic includ...
