double QwtScaleArithmetic::ceil125 ( double x ) [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

Parámetros:

x	Input value

double QwtScaleArithmetic::ceilEps	(	double	value,
		double	intervalSize
	)		`[static]`

Ceil a value, relative to an interval

Parámetros:

value	Value to ceil
intervalSize	Interval size

int QwtScaleArithmetic::compareEps	(	double	value1,
		double	value2,
		double	intervalSize
	)		`[static]`

Compare 2 values, relative to an interval.

Values are "equal", when : $\cdot value2 - value1 <= abs(intervalSize * 10e^{-6})$

Parámetros:

double QwtScaleArithmetic::divideEps	(	double	interval,
		double	steps
	)		`[static]`

double QwtScaleArithmetic::floor125 ( double x ) [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.

Parámetros:

x	Input value

double QwtScaleArithmetic::floorEps	(	double	value,
		double	intervalSize
	)		`[static]`

Floor a value, relative to an interval

Parámetros:

value	Value to floor
intervalSize	Interval size
