Does anyone know if you can specify how many digits are displayed in
the exponent field when you use the %g format specifier?
No. When scientific notation is chosen, %g behaves like %e. The standard
has this to say about %e: "The exponent always contains at least two
digits, and only as many more digits as necessary to represent the
exponent."

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
