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:

double QwtScaleArithmetic::ceilEps (doublevalue, doubleintervalSize) [static]¶

Ceil a value, relative to an interval

Parameters:

See also:

int QwtScaleArithmetic::compareEps (doublevalue1, doublevalue2, doubleintervalSize) [static]¶

Compare 2 values, relative to an interval. Values are 'equal', when : $dot value2 - value1 <= abs(intervalSize * 10e^{-6})$

Parameters:

Returns:

double QwtScaleArithmetic::divideEps (doubleintervalSize, doublenumSteps) [static]¶

Divide an interval into steps. $stepSize = (intervalSize - intervalSize * 10e^{-6}) / numSteps$.PP Parameters:

Returns:

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:

double QwtScaleArithmetic::floorEps (doublevalue, doubleintervalSize) [static]¶

Floor a value, relative to an interval

Parameters:
