s Computer arithmetic and the MathCW library Nelson H. F. Beebe University of Utah Department of Mathematics, 110 LCB Internet e-mail: [email protected] Salt Lake City, UT 84112-0090, USA URL: http://www.math.utah.edu/~beebe/ Abstract This talk describes the significance of specific features of integer and floating-point arithmetic for computation. It discusses the impact of the recent introduction of support for decimal floating-point arithmetic in software and hardware. It sketches the development of a large portable mathematical function library that is a superset of the C99 library, and smoothes the path to future support of octuple precision (256-bit 70D) floating-point software arithmetic on current platforms.

متن کاملLa(OTf)2-amine Grafted-GO as the First Multifunctional Catalyst for the One-pot Three-component Synthesis of α-Aminophosphonates
In this paper, the applicability of immobilized lanthanum (III) triflate on amine grafted graphene oxide [La(OTf)2-amine grafted-GO] as the first multifunctional catalyst is described for the efficient synthesis of α-aminophosphonates by one-pot three-component reaction of carbonyl compounds, substituted anilines and trialkyl phosphites. Various α-aminophosphonates were synthesized in good to h...
متن کاملQuantum Mechanical Calculations of Photovoltaic and Photoelectronic Properties of Oligoselenophene/Fullerene BHJ Solar Cells
To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...
