The value is not truncated even if the result is larger. If the value to be printed is shorter than this number, the result is padded with blank spaces. Minimum number of characters to be printed. Left-pads the number with zeroes ( 0) instead of spaces when padding is specified (see width sub-specifier). By default, if no digits follow, no decimal point is written. Used with a, A, e, E, f, F, g or G it forces the written output to contain a decimal point even if no more digits follow. Used with o, x or X specifiers the value is preceeded with 0, 0x or 0X respectively for values different than zero. If no sign is going to be written, a blank space is inserted before the value. By default, only negative numbers are preceded with a - sign.

Left-justify within the given field width Right justification is the default (see width sub-specifier).įorces to preceed the result with a plus or minus sign ( + or -) even for positive numbers. precision and modifiers (in that order), which are optional and follow these specifications: The format specifier can also contain sub-specifiers: flags, width. The number of characters written so far is stored in the pointed location.Ī % followed by another % character will write a single % to the stream.
The corresponding argument must be a pointer to a signed int. Use the shortest representation: %E or %F Use the shortest representation: %e or %f Scientific notation (mantissa/exponent), uppercase Scientific notation (mantissa/exponent), lowercase
Where the specifier character at the end is the most significant component, since it defines the type and the interpretation of its corresponding argument: It can optionally contain embedded format specifiers that are replaced by the values specified in subsequent additional arguments and formatted as requested.Ī format specifier follows this prototype: Parameters format C string that contains the text to be written to stdout. If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers. Writes the C string pointed by format to the standard output ( stdout).
