How to convert from native variables?

Question

HTML

border-radius: calc(var(--icon-size) / 2) / var(--icon-size);

how to convert from native variables?

trying

$size = 36px;
border-radius: calc(($size/2) / $size); galp

does not compile errors either

Answer 1

$size: 36px;
border-radius: calc(#{($size/2) / $size});

$size: 36px;
$result: ($size/2) / $size;
border-radius: calc(#{$result});

$size: 36px;
border-radius: calc((#{$size}/2) / #{$size});

But none of this makes sense in this case. You can just calculate and insert the value:

$size: 36px;
border-radius: (($size/2) / $size);
