Just for reference, the effect of the alternative style is explained
succinctly in the C99 standard (well, the N1256 draft, anyway):
"For a, A, e, E, f, F, g, and G conversions, the result of converting a
floating-point number always contains a decimal-point character, even if
no digits follow it. (Normally, a decimal-point character appears in the
result of these conversions only if a digit follows it.) For g and G
conversions, trailing zeros are not removed from the result. For other
conversions, the behavior is undefined."
