Answer by juan for Computing digits of irrational exponentiation

I do not think there is an algorithm (or you have to change somethingto allow algorithms that never end with some data). Consider the two numbers $$a=(3/2)^\sqrt{2}=1.77431468418218794421950\dots\quad...

Answer by Gerhard Paseman for Computing digits of irrational exponentiation

The "standard" method should be along the lines of "forming" an approximation of a and b from their digit representations, then computing exp(b* log(a)) using standard routines for approximations. You...

Computing digits of irrational exponentiation

Let us have positive irrational numbers $a$ and $b$ represented by functions $f_a,f_b\colon\mathbb{N}\to\mathbb{N}$ respectively such that $f_a(0)=\left \lfloor{a}\right \rfloor$ and $f_a(i)$, $i>0$...
