Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The <precision> field contains a nonnegative decimal integer
     preceded by a period (.). The value specifies the number of digits
     or characters printed, the number of decimal places, or the number
     of significant digits.
 
     Unlike the width specification, the precision specification can
     cause truncation or rounding of the output.
 
     When <precision> is omitted, the interpretation of the precision
     value and the default depends on the type:
 
          ◄Integer:        d, i, u, o, x, X ►
          ◄Floating-point: e, E, f, g, G    ►
          ◄Character:      c, s             ►
 
     If the precision specification is an asterisk (*), the next
     argument supplies the value. The precision argument, an integer,
     must precede the value being formatted.
