//%d: Signed decimal integers.
//%i: Signed decimal integers.
//%e: Scientific notation (lowercase e).
//%E: Scientific notation (uppercase E).
//%f: Decimal floating point.
//%F: Decimal floating point (C99 only; produces uppercase INF, INFINITY, or NAN when applied to infinity or a value that is not a number. The %f specifier produces lowercase equivalents.)
//%g: Uses %e or %f, whichever is shorter.
//%G: Uses %E or %F, whichever is shorter.
