title: Truncate decimal numbers in Wolfram Mathematica?
body: <p>Is there a quick and easy way to truncate a decimal number, say beyond 4 digits, in MATHEMATICA?</p>
  
  <p>With <code>N[1/6, 4]</code> it rounds to <code>=1.6667</code>.</p>
  
  <p>I want you to cut to <code>1.6666</code>.</p>
  
  <p>Thanks!</p>
