<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Converts the argument to an unsigned 16-bit Integer. The syntax for its use is </p>
<pre class="fragment"> y = uint16(x)
</pre><p> where <code>x</code> is an <code>n</code>-dimensional numerical array. Conversion follows saturation rules (e.g., if <code>x</code> is outside the normal range for an unsigned 16-bit integer of <code>[0,65535]</code>, it is truncated to that range. Note that both <code>NaN</code> and <code>Inf</code> both map to 0. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>The following piece of code demonstrates several uses of <code>uint16</code>.</p>
<pre class="fragment">--> uint16(200)
ans =
200
</pre><p>In the next example, an integer outside the range of the type is passed in. The result is truncated to the maximum value of the data type.</p>
<pre class="fragment">--> uint16(99400)
ans =
65535
</pre><p>In the next example, a negative integer is passed in. The result is truncated to zero.</p>
<pre class="fragment">--> uint16(-100)
ans =
0
</pre><p>In the next example, a positive double precision argument is passed in. The result is the unsigned integer that is closest to the argument.</p>
<pre class="fragment">--> uint16(pi)
ans =
3
</pre><p>In the next example, a complex argument is passed in. The result is the complex unsigned integer that is closest to the argument.</p>
<pre class="fragment">--> uint16(5+2*i)
ans =
5.0000 + 2.0000i
</pre><p>In the next example, a string argument is passed in. The string argument is converted into an integer array corresponding to the ASCII values of each character.</p>
<pre class="fragment">--> uint16('helo')
ans =
104 101 108 111
</pre><p>In the last example, a cell-array is passed in. For cell-arrays and structure arrays, the result is an error.</p>
<pre class="fragment">--> uint16({4})
Error: Cannot perform type conversions with this type
