![]() ![]() The precision, if any, gives the minimum number of digits that must appear if the converted value requires fewer digits, it is padded on the left with zeros. The letters abcdef are used for x conversions the letters ABCDEF are used for X conversions. o,u,x,X The unsigned int argument is converted to unsigned octal ( o), unsigned decimal ( u), or unsigned hexadecimal ( x and X) notation.When 0 is printed with an explicit precision 0, the output is empty. d,i The int argument is converted to signed decimal notation.TheĬonversion specifiers and their meanings are: This gives the minimum number of digits to appear for d, i, o, u, x, and X conversions, the number of digits to appear after the radix character for a, A, e, E, f, and F conversions, the maximum number of significant digits for g and G conversions, or the maximum number of characters to be printed from a string for s conversions.Ī character that specifies the type of conversion to be applied. If the precision is given as just '.', or the precision is negative, the precision is taken to be zero. Result of a conversion is wider than the field width, the field isĮxpanded to contain the conversion result.Īn optional precision, in the form of a period ( '.') followed by an optional decimal digit string. In no case doesĪ non-existent or small field width cause truncation of a field if the Taken as a '-' flag followed by a positive field width. If the left-adjustment flag has been given). The field width, it will be padded with spaces on the left (or right, If the converted value has fewer characters than A overrides a space if both are used.Īn optional decimal digit string (with nonzero first digit) specifying a ![]() By default a sign is used only for negative numbers.
