The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

EInvalidOp with message 'Invalid floating point operation' -- cannot determine cause of exception

Asked by prufrock17 in C++ Builder

Tags: point, floating, invalid, operation, einvalidop


Hi,

All right, I'm stumped on this one.  I am using C++ Builder 6, and I keep getting the 'Invalid floating point operation' exception when I execute a certain line of code.

I am calling the following member function:

        AmpHoursRemainingSet(0.0);

which looks like

void MyClass::AmpHoursRemainingSet(float value)
{

  if (0.0 > 3.3)
    {
        value = AD_NEW_BATTERY_MAXIMUM_AMP_HOUR_CAPACITY;
    }
 
  if (value > 3.3)
    {
        value = AD_NEW_BATTERY_MAXIMUM_AMP_HOUR_CAPACITY;
    }

}

Whenever the second if statement is executed, the exception occurs.  (I put the first if statement in to verify the values are  not causing the problem).

I have absolutely no idea why this may be occurring -- or how I can go about debugging this.  I have not had any problems with floating point types in Borland before, so I do not know why it is occurring with this application.

Also, this happens in a number of spots -- sometimes with comparisons, sometimes with assignments.  If I hard-code numbers in, the problem disappears.

Any thoughts/comments would be great.

Thanks,
Jeff
