But isn't the point of using an ascii file to make it human-readable?
And editable? If not, you might as well just write the actual byte
representation.
Allowing numbers to run into one another in the special case of 13-char
negative floats isn't so attractive to me. What if I write "3-4-5"?
Should that make sense?
