No, not if you want to expand the complexity. Every irrational number you
would probably need you could express in terms of pi, e, sqrt, cube roots,
sin, and rational numbers.

Depending on what you're doing, it may be fast enough. My question is
where do you prefer 12038838484884757761111111111456646243627 /
12883848484058534671734792837598275927 to the equivelent decimal
solution.
