Math operator / don't work

Hello, i use last version gulp-sass 4.0.2 SASS .class { line-heght: 14 / 10; } compile to CSS .class { line-heght: 14 / 10; } But this should be line-heght: 1.4;

I use defaul gulp settings:

// Process, lint, and minify Sass files
var buildStyles = function (done) {

// Run tasks on all Sass files
return src(paths.styles.input)
	.pipe(sass({
		outputStyle: 'expanded',
		sourceComments: false
	}))
	.pipe(postcss([
		prefix({
			cascade: true,
			remove: true
		})
	]))
	.pipe(header(banner.main, {package: package}))
	.pipe(dest(paths.styles.output))
	.pipe(rename({suffix: '.min'}))
	.pipe(postcss([
		minify({
			discardComments: {
				removeAll: true
			}
		})
	]))
	.pipe(dest(paths.styles.output));

};

The symbol / is used in shorthand CSS properties. The behavior observed by OP is correct.

@xzyfer this is also unrelated to gulp-sass.
