Is everything a rational function?

Abstract
There's an idea going back at least to Kirchberger in 1902 that since the only operations we can ultimately compute are +, -, *, and /, all of numerical computation must reduce to rational functions. I've been looking into this idea and it has led in some interesting directions.
