     e, E     The precision specifies the number of digits to be
              printed after the decimal point. The last digit is
              rounded. Default precision is 6; if the precision value
              is 0 or no number follows the period (.), no decimal
              point is printed.
 
     f        The precision value specifies the number of digits after
              the decimal point. If a decimal point appears, at least
              one digit is printed before it. The value is rounded.
              Default precision is 6; if the precision value is 0 or
              no number follows the period (.), no decimal point is
              printed.
 
     g, G     The precision specifies the maximum number of
              significant digits. By default, six significant digits
              are printed, less any trailing zeros that are truncated.
