<h1>ds_set_precision</h1>
<p>When comparing values, for example when searching in a map or sorting a list, GameMaker Studio 2 must decide when two values are equal. For strings and integer values this is clear but for real numbers, due to floating
point round-off errors, seemingly equal numbers can easily become unequal. For example, it's possible that <b>(5 / 3) * 3</b> will <i>not</i> be equal to 5! To help avoid this, a precision value
is used on all real number functions, and when the <i>difference between two numbers is smaller</i> than this precision they are considered equal. The default a precision of 0.0000001 is used for all data structure functions
unless changed by this function.</p>
<p class="note"><b>NOTE</b>: This precision is used in all data structures but not in other comparisons in GML!</p>

<h4>Syntax:</h4>
<p class="code">ds_set_precision(prec);</p>
<table>
<tbody>
<tr>
<th>Argument</th>
<th>Description</th>
</tr>
<tr>
<td>prec</td>
<td>The precision value (default 0.0000001)</td>
</tr>
</tbody>
</table>
<p> </p>
<h4>Returns:</h4>
<p class="code">Returns:N/A</p>
<p> </p>
<h4>Example:</h4>
<p class="code">ds_set_precision(0.0001);</p>
<p>The above code will change the default precision setting for all data structure functions.</p>
