Carefully describe the process of program testing

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(2) is replaced with the constant

2.0; in other words, the line

radius = diameter/static_cast(2);

is replaced with the line

radius = diameter/2.0;

Are these two possible function definitions black-box equivalent?
