Round up a variable with Shopify Liquid
<p>I wish to assign a dummy variable to a math value so I can then take the ceiling.</p>

<p>My current code is:</p>

<pre><code>{% if variant.compare_at_price &gt; variant.price %} 
    SAVE {{ variant.compare_at_price | minus:variant.price | times:100 | divided_by:variant.compare_at_price }}%
{% endif %}
</code></pre>

<p>Output is SAVE 20% (for example, but if it's 19.99 it'll be 19% rather than 20%)</p>

<p>But I want to call:</p>

<pre><code>x= {{ variant.compare_at_price | minus:variant.price | times:100 | divided_by:variant.compare_at_price }}%
</code></pre>

<p>then take <code>{{ x | ceil }}</code></p>

<p>How do I assign <code>x</code>?</p>
