These spaces are added at the beginning by default unless the flag FormattableFlags.LEFT_JUSTIFY is set, which denotes that padding should be added at the end. If width is -1, then minimum length is not enforced.
precision the maximum number of characters that can be written to the output. The length of the output is trimmed down to this size before the width padding is applied. If the precision is -1, then maximum length is not enforced.
