title: How to loop through a range of decimal numbers in bash?
body: <p>I'd like to generate a sequence of equally spaced decimal numbers.</p>
  
  <p>For example, I want to <code>echo</code> all numbers between <code>3.0</code> and <code>4.5</code>, with step <code>0.1</code>. I tried <code>$ for i {3.0..4.5..0.1}; do echo $i; done</code>, but this gives an error.</p>
  
  <p>I also tried <code>$ for i in $(seq 3.0 4.5 0.1); do echo $i; done</code> but nothing happens.</p>
