Mocking functions returning floating point values

Sample262.1below illustrates how to mock a function that is returning a double and how to use the macros MOCK_VALUE and MOCK_VALUE_FP to access both representations of the simulate value.

  #define PI (4.0 * atan( 1.0 ))

  double mock_pi() {
    return MOCK_VALUE_FP;
  } 

  double integer_mock_pi() {
    return MOCK_VALUE;
  }
    
  void test_deg2rad(void) {
    EXPECT_MOCK( pi, mock_pi, PI );
    VALIDATE_FP    ( deg2rad(360), 2*PI);
    EXPECT_MOCK( pi, integer_mock_pi, PI );
    VALIDATE       ( deg2rad(360), 2*PI);
  }

It is safe to mix the usage of these macros with both integers or floating points values, i.e if MOCK_VALUE_FP is used as an integer value, the compiler will cast it to an integer value, and if MOCK_VALUE is used as a floating point value, it will be cast to an floating point value.
