title: Generate a Random Number within a Range
body: <p>I have done this before, but now I'm struggling with it again, and I think I am not understanding the math underlying the issue.</p>
  
  <p>I want to set a random number on within a small range on either side of <code>1</code>. Examples would be <code>.98</code>, <code>1.02</code>, <code>.94</code>, <code>1.1</code>, etc. All of the examples I find describe getting a random number between <code>0</code> and <code>100</code>, but how can I use that to get within the range I want?</p>
  
  <p>The programming language doesn't really matter here, though I am using Pure Data. Could someone please explain the math involved?</p>
