title: How to convert a number always to be negative?
body: <p><code>Math.abs()</code> converts any number to positive. Is there also a function (that I might be missing) that supports the other way around: convert any number (no matter of sign) to a negative number?</p>
  
  <p>The only thing I could imagine is:
  <code>Math.abs(number) * -1</code></p>
