title: Simple way to check if double value is greater than zero
body: <p>I have a double variable(<strong>employeeSalary</strong>) and I want to check if this value is greater than(>) zero(<strong>0</strong>). I can think of very naive way to write this code but I am not sure if for <strong>double</strong> data type this is correct way to write.</p>
  
  <pre><code>if(employeeSalary &gt; 0){
    // Employee salary is greater than zero.
  }else{
    // Employee salary is less than or equal to zero.
  }
  </code></pre>
  
  <p>Can anyone please tell me if this approach works?</p>
