# number-leading-zero Require or disallow a leading zero for fractional numbers less than 1. <!-- prettier-ignore --> ```css a { line-height: 0.5; } /** ↑ * This leading zero */ ``` This rule ignores mixin parameters in Less. The [`fix` option](../../../docs/user-guide/usage/options.md#fix) can automatically fix all of the problems reported by this rule. ## Options `string`: `"always"|"never"` ### `"always"` There _must always_ be a leading zero. The following patterns are considered violations: <!-- prettier-ignore --> ```css a { line-height: .5; } ``` <!-- prettier-ignore --> ```css a { transform: translate(2px, .4px); } ``` The following patterns are _not_ considered violations: <!-- prettier-ignore --> ```css a { line-height: 0.5; } ``` <!-- prettier-ignore --> ```css a { transform: translate(2px, 0.4px); } ``` ### `"never"` There _must never_ be a leading zero. The following patterns are considered violations: <!-- prettier-ignore --> ```css a { line-height: 0.5; } ``` <!-- prettier-ignore --> ```css a { transform: translate(2px, 0.4px); } ``` The following patterns are _not_ considered violations: <!-- prettier-ignore --> ```css a { line-height: .5; } ``` <!-- prettier-ignore --> ```css a { transform: translate(2px, .4px); } ```
