Implementing the transcendental functions in Ivy
Summary
An in-depth look at implementing high-precision transcendental functions in Ivy, including sine, cosine, exponential, logarithm, arctangent, and the gamma function. The post surveys Taylor series methods, argument reduction challenges, and three major gamma-approximation techniques (Lanczos, Spouge, and Causley interpolation), with Ivy code snippets and performance notes. It also reflects on exact arithmetic and building the necessary coefficient machinery within Ivy.
