title: sed rounding a number to 2 decimals
body: <p>I have a number i.e. 123.456789 and my question is how to round this to two decimals after dot, so it look like 123.46 using sed? Any ideas?
  Alternatively, how to cut the rest after 2 decimals so in the end it would look like this: 123.45?
  Thanks in advance!</p>
