Member Function Documentation
   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

       See also:
	   floorEps()

   int QwtScaleArithmetic::compareEps (doublevalue1, doublevalue2, doubleintervalSize) [static]
       Compare 2 values, relative to an interval. Values are 'equal', when : $

       Parameters:
	   value1 First value to compare
	   value2 Second value to compare
	   intervalSize interval size

       Returns:
	   0: if equal, -1: if value2 > value1, 1: if value1 > value2

   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

       See also:
	   floorEps()
