<div class="desc"><p>Returns the tangent of <code>radians</code>, computed as <code>Math.sin(radians) / Math.cos(radians)</code> in fixed-point. Near odd multiples of <code>pi/2</code> the cosine approaches zero and the result grows without bound, so guard those angles. For most gameplay, <code>Math.sin</code>/<code>Math.cos</code> are what you want; <code>tan</code> is here for slopes and field-of-view math.</p></div>
