Revert "Add math min/max for Float and Value"

This reverts commit 078a0a6999a916def004211a4c35a9e1b32ae355.

On closer inspection, I'm not sure these values for float min/max
make sense. Why is it max instead of true_max? Why isn't it positive
and negative infinity?

Let's discuss further before committing to these changes.
