   double QwtScaleArithmetic::ceil125 (doublex) [static] Find the smallest value out of {1,2,5}*10^n with an
       integer number n which is greater than or equal to x
       Parameters:
           x Input value

   double QwtScaleArithmetic::ceilEps (doublevalue, doubleintervalSize) [static] Ceil a value, relative to an
       interval
       Parameters:
           value Value to ceil
           intervalSize Interval size

   double QwtScaleArithmetic::divideEps (doubleintervalSize, doublenumSteps) [static]
       Divide an interval into steps. $stepSize = (intervalSize - intervalSize * 10e^{-6}) / numSteps$.PP
       Parameters:
           intervalSize Interval size
           numSteps Number of steps

       Returns:
           Step size

   double QwtScaleArithmetic::floor125 (doublex) [static]
       Find the largest value out of {1,2,5}*10^n with an integer number n which is smaller than or equal to x.
       Parameters:
           x Input value

   double QwtScaleArithmetic::floorEps (doublevalue, doubleintervalSize) [static] Floor a value, relative to an
       interval
       Parameters:
           value Value to floor
           intervalSize Interval size
