I know floats are full of scary corner cases, but… Assuming tens of bytes per an if statement, hundreds of corner cases just in formatting? Is it really that bad?

A naive implementation would be small, but a correct implementation (with some concrete definition of "correct") will need a sizable data table. I know this because I wrote that part of code [1] and somehow it is still in the std even though other algorithms now exist [2].
