◄Up► ◄Contents► ◄Index► ◄Back► ─────Run-Time Library─────────────────────────────────────────────────────── 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. -♦-
