description:
Made algebraic operators compute float operations
on the fly instead of representing them as Sum etc.
Simplifies some expressions created by algorithms.
Still not sorting operands to discover 2+2 in "2+n+2",
since this has other side effects.

(+ Some minor improvements to latex output.)
