Re: [Dev-C++] Arry dimensions

[<Mat...@bm...>]

I use this function which I got from S.C Wong from code project. It will
round a double to two decimal places. You need to include math.h to use
it though.
 
// rounds a double variable to nPlaces decimal places
double Round(double dbVal, int nPlaces /* = 0 */)
{
    const double dbShift = pow(10.0, nPlaces);
    return  floor(dbVal * dbShift + 0.5) / dbShift; 
}   

 

Hope that helps,

 

MT
