| + | ====== Float padding ====== | ||
| + | |||
| + | The field //width// includes the decimal point and the fractional portion (and the sign, if it's negative). | ||
| + | |||
| + | |||
| + | ===== Padding negative numbers ===== | ||
| + | Flags: | ||
| + | * ''-'' Left-justify the given field width (see Width below). Right justification is the default. | ||
| + | * ''+'' Forces a "+" sign to precede a number. Has no effect on negative numbers. | ||
| + | * ''(space)'' One blank space is inserted before a positive number, while negative numbers are unaffected. This is useful for making positive and negative numbers vertically align in a visual stacked list. | ||
