String -> Float with str2float()
Float -> String with printf()
When would you need Float -> Int? You can actually use
printf(".0f", float), and rely on automatic String to Int conversion,
but it's clumsy.

The number you see is the largest int value or a special value for
floats which is INFINITY. It has always worked this way for Ints, don't
know if it is such a good idea to do differently for floats. Although I
would rather get the maximum value, INFINITY doesn't appear to be close
to infinity :-). I suppose I should use MAXFLOAT instead.

I don't see an argument to printf() to get this.
