Function Documentation

◆ Approx() [1/2]

double Approx	(	double	a,
		double	b,
		double	eps
	)

Return True if a is approximately the same as b. I.E. |a-b| < eps

Definition at line 126 of file util.cpp.

◆ Approx() [2/2]

bool Approx	(	int	n,
		double *	a,
		double *	b,
		double *	eps
	)

Return True if list/tuple/array a=(a1,a2,...) is approximately the same as b=(b1,b2,...). I.E. |a_i-b_i| < eps[i]

Definition at line 132 of file util.cpp.

◆ CompareReleases()

int CompareReleases	(	char const *	rev1,
		char const *	rev2
	)

compare release strings

compare release strings rev1 and rev2.

Returns: -1,0, or 1 if rev1 is older, equal or newer than rev2

Parameters

rev1	- a release string like "0.0.1.5" or "0.0.1.11-a"
rev2	- another release string

Example:

CompareReleases( "0.0.1.5", "0.0.1.5" ) ==> 0
CompareReleases( "0.0.1.5", "0.0.1.4" ) ==> 1
CompareReleases( "0.0.1.5", "0.0.2.1" ) ==> -1
CompareReleases( "0.0.1.5", "0.0.1.5-a" ) ==> -1

Definition at line 236 of file util.cpp.

◆ DegToRad()

double DegToRad ( double d )

Return d in deg converted to rad

Definition at line 143 of file util.cpp.

◆ InIndex()

NAMESPACE_SDH_START bool InIndex	(	int	v,
		int	max
	)

Return True if v is in range [0 .. max[

Definition at line 74 of file util.cpp.

◆ InRange() [1/2]

bool InRange	(	double	v,
		double	min,
		double	max
	)

Return True if v is in range [min .. max]

Definition at line 80 of file util.cpp.

◆ InRange() [2/2]

bool InRange	(	int	n,
		double const *	v,
		double const *	min,
		double const *	max
	)

Return True if in list/tuple/array v=(v1,v2,...) each v_i is in range [min_i..max_i] with min = (min1, min2,...) max = (max1, max2, ..)

Definition at line 86 of file util.cpp.

◆ NumerifyRelease()

std::vector<int> NumerifyRelease ( char const * rev )

return a vector of integer numbers for a release string rev

Parameters

rev	release string like "0.0.1.11-a"

Returns: a vector of integer numbers like [0,0,1,11,1]

Definition at line 177 of file util.cpp.

◆ RadToDeg()

double RadToDeg ( double r )

Return r in rad converted to deg

Definition at line 149 of file util.cpp.

◆ SleepSec()

void SleepSec ( double t )

Sleep for t seconds. (t is a double!)

Definition at line 155 of file util.cpp.

◆ ToRange() [1/4]

double ToRange	(	double	v,
		double	min,
		double	max
	)

Return v limited to range [min .. max]. I.e. if v is < min then min is returned, or if v > max then max is returned, else v is returned

Definition at line 97 of file util.cpp.

◆ ToRange() [2/4]

void ToRange	(	int	n,
		double *	v,
		double const *	min,
		double const *	max
	)

Limit each v_i in v to range [min_i..max_i] with min = (min1, min2,...) max = (max1, max2, ..) This modifies *v!

Definition at line 105 of file util.cpp.

◆ ToRange() [3/4]

void ToRange	(	std::vector< double > &	v,
		std::vector< double > const &	min,
		std::vector< double > const &	max
	)

Limit each v_i in v to range [min_i..max_i] with min = (min1, min2,...) max = (max1, max2, ..) This modifies v!

Definition at line 114 of file util.cpp.

◆ ToRange() [4/4]

void ToRange	(	cSimpleVector &	v,
		std::vector< double > const &	min,
		std::vector< double > const &	max
	)
