The equal sign (<span class="parmname" id="dli_08_0191__parmname1200387235114232"><b>=</b></span>) is not recommended for comparing two values of the double type. You are advised to obtain the absolute value by subtracting these two values of the double type and determine whether they are the same based on the absolute value. If the absolute value is small enough, the two values of the double data type are regarded equal. For example:<pre class="screen" id="dli_08_0191__s03cbcd5c5d7e463aaecf73ac2ff5a820">abs(0.9999999999 - 1.0000000000) &lt; 0.000000001 //The precision decimal places of 0.9999999999 and 1.0000000000 are 10, while the precision decimal place of 0.000000001 is 9. Therefore, 0.9999999999 can be regarded equal to 1.0000000000.</pre>
