title: Do power functions run in constant time?
body: <p>When I use power functions like Math.Pow(double x, double y) in C# or the math.h pow-function in C++ do these run in constant time? </p>
  
  <p>The reason I am asking is because I want to know if a "precalculated" bézier-function on the form (1-t)^n*p0 + ... + t^(n) * pN could run in linear time which could then be faster than an implementation of De Casteljaus algorithm taking control points and t as parameters. </p>
