ABSTRACT

In the past few chapters, I've shown algorithms for computing almost all the fundamental functions: square root, sine, cosine, and arctangent. I gave you optimized, thoroughly tested implementations useful in embedded-system applications. I've also shown how to compute the remaining trig functions, such as tangent, arcsine, and arccosine, from the functions given. Two fundamental functions remain to be discussed: the logarithm and its antifunction, also known as the exponential function.
