<p dir="auto">Would it not be better just to use that then? Yes I can prove using logarthmic identities that what you've written is the same but it's not clear why you prefer the transformed version?</p>
<p dir="auto">I also suspect the <code class="notranslate">Math.max</code> is no longer needed as it can't go negative for any sane zoom - it was needed before because log10 breaks down for zoom zero...</p>
