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.

+ A sign ( + or -) always be placed before a number produced by a signed conversion.

' ' (a space) A blank should be left before a positive number (or empty string) produced by a signed conversion.

(The default is right justification.) Except for n conversions, the converted value is padded on the right with blanks, rather than on the left with blanks or zeros.

- The converted value is to be left adjusted on the field boundary.

For other conversions, the behavior is undefined. If a precision is given with a numeric conversion (d, i, o, u, x, and X), the 0 flag is ignored. If the 0 and - flags both appear, the 0 flag is ignored. For d, i, o, u, x, X, a, A, e, E, f, F, g, and G conversions, the converted value is padded on the left with zeros rather than blanks. For other conversions, the result is undefined. For g and G conversions, trailing zeros are not removed from the result as they would otherwise be. For a, A, e, E, f, F, g, and G conversions, the result will always contain a decimal point, even if no digits follow it (normally, a decimal point appears in the results of those conversions only if a digit follows). For x and X conversions, a nonzero result has the string '0x' (or '0X' for X conversions) prepended to it. For o conversions, the first character of the output string is made zero (by prefixing a 0 if it was not zero already).

\# The value should be converted to an ``alternate form''.

The character % is followed by zero or more of the following flags:

The arguments must correspond properly (after type promotion) with theĬonversion specifier, and are used in the order given. More flags, an optional minimum field width, and an optional precision. In between there may be (in this order) zero or EachĬonversion specification is introduced by the character %, and ends with aĬonversion specifier.
