All float specifiers (e, E, f, g, G) are treated identically by the scanf
functions. When scanning floats, they always recognize all float formats.
One other thing about %g on output is that it automatically strips trailing
zeros, which %f doesn't do. So it can actually be quite useful for printing
things that don't trigger it to go into scientific notation.
