That, frankly, is pretty ludicrous. The reserved mantissa width should
at least be constrained to the actually available precision of the data
type. If it isn't, there is no useful way to output a variable with
minimal width. Using ~S instead results in the much more reasonable
"3.333333333333333e99" but it will not convert fractions to a floating
point representation:

scheme@(guile-user)> (format #f "~S" (/ 10000000000000000000000000000000 3))
