Member Function Documentation

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::roundToDigits	(	double	number,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method not just cut off parameter specified number of less significant digits. It adds 1 to last not-cut digit if most significant cut digits was 5 or greater.

Returns:

double

Parameters:

	number	double
	numberOfDigits	int

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::roundToDigits	(	double	number,
		double	formatNumberForRounding,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method round number in this manner that digits that represent the same order as formatNumberForRounding are rounded as method roundToDigits(double, int) do it.

roundToDigits(123456,123,1) return 123500 roundToDigits(123416,123,1) return 123400

Returns:

double

Parameters:

	number	double
	numberOfDigits	int
	formatNumberForRounding	double

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::roundUpToDigits	(	double	number,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method not just cut off parameter specified number of less significant digits. Rounded value is equall or greather than old value.

Returns:

double

Parameters:

	number	double
	numberOfDigits	int

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::roundUpToDigits	(	double	number,
		double	formatNumberForRounding,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method round number in this manner that digits that represent the same order as formatNumberForRounding are rounded as method roundUpToDigits(double, int) do it.

roundToDigits(123456,123,1) return 123500 roundToDigits(123416,123,1) return 123500

Returns:

double

Parameters:

	number	double
	numberOfDigits	int
	formatNumberForRounding	double

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::roundUpToTenth

(

double

number

)

[inline, static]

This method round parameter specified number to power of ten, which is first, greather than it.

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::truncToDigits	(	double	number,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method just cut off parameter specified number of less significant digits.

Returns:

double

Parameters:

	number	double
	numberOfDigits	int

static double com::cosylab::gui::components::r2::chart::accessories::RoundDoubleToDouble::truncToDigits	(	double	number,
		double	formatNumberForRounding,
		int	numberOfDigits
	)			throws IllegalArgumentException [inline, static]

This method round number in this manner that digits that represent the same order as formatNumberForRounding are rounded as method roundUpToDigits(double, int) do it.

roundToDigits(123456,123,1) return 123400 roundToDigits(123416,123,1) return 123400

Returns:

double

Parameters:

	number	double
