title: Find nth Root of a number in C++
body: <p>I'm trying to make a maths library and one of the functions finds a nth root of a float.</p>
  
  <p>My current expression is - </p>
  
  <pre><code>value = value ^ 1/rootValue
  </code></pre>
  
  <p>but I'm getting an error because I'm using a float.
  Is there another method of solving this?</p>
