Banker's rounding

[matheww]

you will get exactly that, all you have to do is to try it out
round( 8.925, 2 ); and see what you get

from the debug..

value = 8.925 result = 8.92
the function..

double bankround(double value, int precision = 2){
  double rv = long( value * pow(10, precision) + 0.5 )/ pow(10, precision );
  qDebug() << "value = " << value << " result = " << rv;
  return  rv ;
}

double bankround(double value, int precision = 2){
  double rv = long( value * pow(10, precision) + 0.5 )/ pow(10, precision );
  qDebug() << "value = " << value << " result = " << rv;
  return  rv ;
}
