title: C - Exponentiation with non integer exponent
body: <p>Is there a neat way to achieve this without using the pow()-function? Say wanting to calculate 2^(2.5).</p>
  
  <p>EDIT: Perhaps pow() is the way to go after all. I was hoping to create a function of my own using only the four common operations to solve it. (Reason being I like to do things manually)</p>
