Consider two possible definitions for the function unitprice. One is the

definition given in Display 4.10. The other definition is the same except

that the type cast static_cast<double>(2) is replaced with the constant

2.0, in other words, the line

radius = diameter/static_cast<double>(2);

is replaced with the line

radius = diameter/2.0;

Are these two possible function definitions black-box equivalent?

Yes, the function would return the same value in either case, so the two

definitions are black-box equivalent.

Post the discussion to improve the above solution.
