Printf

1. @printf([io::IOStream], "%Fmt", args...)

Print args using C printf style format specification string, with some caveats: Inf and NaN are printed consistently as Inf and NaN for flags %a, %A, %e, %E, %f, %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 IOStream may be passed as the first argument to redirect output.

1. julia> @printf("%f %F %f %F\n", Inf, Inf, NaN, NaN)
2. Inf Inf NaN NaN

5. julia> @printf "%.0f %.1f %f\n" 0.5 0.025 -0.0078125
6. 1 0.0 -0.007813
