Inside Your Calculator: From Simple Programs to Significant Insights

Inside Your Calculator: From Simple Programs to Significant Insights by Gerald R. Rising

Wiley-Interscience | 2007-07-16 | ISBN:0470114010 | 304 pages | PDF | 12 MB

Many of us want to understand how the technological instruments that so pervade modern society operate. This book answers questions about one of those devices: the scientific calculator. Calculator keys seem to work like magic. They tell us, for example, that the cosine of 56° is 0.559192903. This book explores the simple internal calculator processes (called algorithms or programs) that produce this and similar results. Although the text focuses on the calculator keys that compute powers, roots, logarithms, and trigonometry functions, insights are also provided into simple programming, conversion between decimal and binary numeration, and perhaps most important, the structure of our numeration systems.
