Printf

Print args using C printf style format specification string, with some caveats: Inf and NaN are printed consistently as Inf and for flags %a, %A, %e, %E, %f, , %g, and %G. Furthermore, if a floating point number is equally close to the numeric values of two possible output strings, the output string further away from zero is chosen.

Optionally, an may be passed as the first argument to redirect output.
