title: Update all WooCommerce product prices to 2 decimals in database
body: <p>Many of my products have prices like <code>£3.4560</code> etc. I need them to rounded and stripped to just 2 in the database. </p>
  
  <p>The output of 2 decimal places in WooCommerce is not enough and fails to work with a Tax Toggle plugin. </p>
  
  <p>Is there a database query that can do this? </p>
  
  <p>I've seen some bits on Rounding and Truncate but not sure how to execute this as my knowledge is poor.</p>
  
  <p>Any help is appreciated. </p>
