<!-- $$$QPointF-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QPointF class defines a point in the plane using floating point precision.</p>
<p>A point is specified by a x coordinate and an y coordinate which can be accessed using the <a href="qpointf.html#x">x</a>() and <a href="qpointf.html#y">y</a>() functions. The coordinates of the point are specified using floating point numbers for accuracy. The <a href="qpointf.html#isNull">isNull</a>() function returns true if both x and y are set to 0.0. The coordinates can be set (or altered) using the <a href="qpointf.html#setX">setX</a>() and <a href="qpointf.html#setY">setY</a>() functions, or alternatively the <a href="qpointf.html#rx">rx</a>() and <a href="qpointf.html#ry">ry</a>() functions which return references to the coordinates (allowing direct manipulation).</p>
<p>Given a point <i>p</i>, the following statements are all equivalent:</p>
<pre class="cpp"> <span class="type">QPointF</span> p;
p<span class="operator">.</span><a href="qpointf.html#setX">setX</a>(p<span class="operator">.</span>x() <span class="operator">+</span> <span class="number">1.0</span>);
p <span class="operator">+</span><span class="operator">=</span> <span class="type">QPointF</span>(<span class="number">1.0</span><span class="operator">,</span> <span class="number">0.0</span>);
p<span class="operator">.</span><a href="qpointf.html#rx">rx</a>()<span class="operator">+</span><span class="operator">+</span>;</pre>
<p>A QPointF object can also be used as a vector: Addition and subtraction are defined as for vectors (each component is added separately). A QPointF object can also be divided or multiplied by an <tt>int</tt> or a <tt>qreal</tt>.</p>
<p>In addition, the QPointF class provides a constructor converting a <a href="qpoint.html">QPoint</a> object into a QPointF object, and a corresponding <a href="qpointf.html#toPoint">toPoint</a>() function which returns a <a href="qpoint.html">QPoint</a> copy of <i>this</i> point. Finally, QPointF objects can be streamed as well as compared.</p>

<p>Returns true if both the x and y coordinates are set to +0.0; otherwise returns false.</p>
<p><b>Note:</b> Since this function treats +0.0 and -0.0 differently, points with zero-valued coordinates where either or both values have a negative sign are not defined to be null points.</p>

<p>Returns the sum of the absolute values of <a href="qpointf.html#x">x</a>() and <a href="qpointf.html#y">y</a>(), traditionally known as the "Manhattan length" of the vector from the origin to the point.</p>
