Multiple Precision in JavaScript: Rational Arithmetic III

Elementary Functions: Second Try

Not that I found the code for the rational exponential function I wrote (that’s lost) but I found it unfair to say “too slow” without giving a reason, so i did it again, for exp() and log(). Continue reading

Multiple Precision in JavaScript: Rational Arithmetic II

Elementary Functions

While trying to implement even the most basic elementary functions, like square root, nth-root and the exponential function I had to admit that the Bigrational library is just too slow. Square and nth-root work ok, but the exponential function is of not much use with that low speed it needs floating point arithmetic. Yes, I am working at it.

But all of that is no reason to drop the whole mess completely as you might have seen if you took a look at the Bigrational library. Continue reading
