title: How do I take all values in a column and change their values
body: <p>There are a lot of questions on how to multiply all values by some other cell or to move all values to another cell based on some value, but what I want is to take, in the example image below:</p>
  <p><a href="https://i.stack.imgur.com/ZApU0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZApU0.png" alt="enter image description here" /></a></p>
  <p>All the values that I have selected and divide by 2. I do not want another column, I just want to change all those values in the spread sheet and divide them by 2, the values themselves should change.</p>
  <p>I have not found an answer for this any where and I sure it is super simple. For example, in:</p>
  <p><code>base_damage_mod</code> selected column, 0.03 would become: 0.015.</p>
  <p>The only way I know to do this is manually, and that's a lot of work ...</p>
  <p><strong>Whats the easiest way to do this?</strong></p>
