Best way to put variables inside of calc?

Right now I’m doing width: s('calc(100% * %s)', $fraction) but that gets really hairy when I have several variables.

We should probably standardize variable interpolation as well. I think Sass does this pretty well. Their version looks like: width: calc(100% * #{$fraction}); and is much more readable/enjoyable to work with.

You can simplify it a bit:

width: 'calc(100% * %s)' % $fraction

We’ll change syntax of interpolation (see #728), so Sass’ variant will be possible.

@Panya Thoughts on adding better interpolation?

Something similar to this syntax would be awesome:

$fraction: 1/2

.column
  width: calc(100% * {$fraction})

// returns
.column {
  width: calc(100% * 1/2); // note it doesn't convert 1/2 to .5 automagically
}
