  - ### Format

    public Format​(java.lang.String s)
    Formats the number following printf conventions. Main limitation: Can only handle one format parameter at a time Use multiple Format objects to format more than one number
    Parameters:
      `s` - the format string following printf conventions The string has a prefix, a format code and a suffix. The prefix and suffix become part of the formatted output. The format code directs the formatting of the (single) parameter to be formatted. The code has the following structure
      - a % (required)
      - a modifier (optional)
        +
          forces display of + for positive numbers
        0
          show leading zeroes
        -
          align left in the field
        space
          prepend a space in front of positive numbers
        #
          use "alternate" format. Add 0 or 0x for octal or hexadecimal numbers. Don't suppress trailing zeroes in general floating point format.
      - an integer denoting field width (optional)
      - a period followed by an integer denoting precision (optional)
      - a format descriptor (required)
        f
          floating point number in fixed format
        e, E
          floating point number in exponential notation (scientific format). The E format results in an uppercase E for the exponent (1.14130E+003), the e format in a lowercase e.
        g, G
          floating point number in general format (fixed format for small numbers, exponential format for large numbers). Trailing zeroes are suppressed. The G format results in an uppercase E for the exponent (if any), the g format in a lowercase e.
        d, i
          integer in decimal
        x
          integer in hexadecimal
        o
          integer in octal
        s
          string
        c
          character
    Throws:
      `java.lang.IllegalArgumentException` - if bad format
