Error:Literal of type double cannot be implicitly converted to type `float'. Add suffix `f' to create a literal of this type

I am creating a script that can solve equations for you and right now I'm working on a function that can find the circumference of a circle. public float radiusCircuference; private float pi = 3.14; private float cCircuference; cCircuference = radiusCircuference * pi * 2; It comes up with the error: Literal of type double cannot be implicitly converted to type `float'. Add suffix `f' to create a literal of this type Can someone help please? Thanks in advance
