   double QwtScaleArithmetic::ceilEps (double value, double intervalSize) [static]
       Ceil a value, relative to an interval

       Parameters:
           value Value to be ceiled
           intervalSize Interval size

       Returns:
           Rounded value

   double QwtScaleArithmetic::divideEps (double intervalSize, double numSteps) [static]
       Divide an interval into steps. $stepSize = (intervalSize - intervalSize * 10e^{-6}) /
       numSteps$

       Parameters:
           intervalSize Interval size
           numSteps Number of steps

       Returns:
           Step size

   double QwtScaleArithmetic::divideInterval (double intervalSize, int numSteps, uint base)
       [static]
       Calculate a step size for a given interval

       Parameters:
           intervalSize Interval size
           numSteps Number of steps
           base Base for the division ( usually 10 )

       Returns:
           Calculated step size

   double QwtScaleArithmetic::floorEps (double value, double intervalSize) [static]
       Floor a value, relative to an interval

       Parameters:
           value Value to be floored
           intervalSize Interval size

       Returns:
           Rounded value
