Vector::Trunc Method — MtxVec

Overload List

#	Signature	Description
1	TMtxVec Trunc() const*;	Rounds a real number towards zero.
2	TMtxVec Trunc(int* Index, int Len) const;	Truncate calling object elements [Index]..[Index+Len-1] in-place.
3	TMtxVec Trunc(TMtxVec Src) const;	Truncate all Src object elements and store the results in calling object elements.
4	void Trunc(DewArray<int> &Dst) const;	Truncate all calling object elements and store the result in the Dst integer array.
5	TMtxVec Trunc(TMtxVec Src, int SrcIndex, int Index, int Len) const;	Truncate Src object elements [SrcIndex]..[SrcIndex+Len-1] and store the results to calling object elemenents [Index]..[Index+Len-1].

Overload 1: TMtxVec *Trunc() const;

Rounds a real number towards zero.

Remarks:

Rounds all calling object elements towards zero to an integer and stores the result in the calling object again as floating point numbers.

Overload 2: TMtxVec *Trunc(int Index, int Len) const;

Truncate calling object elements [Index]..[Index+Len-1] in-place.

#	Name	Type	Description
1	Index	int
2	Len	int

Remarks:

An exception is raised if array borders are overrun/underrun.

Declared in Dew::Math::Vector · Dew.Math/MtxExpr.h · Cross-compiler

Overload 3: TMtxVec Trunc(TMtxVec Src) const;

Truncate all Src object elements and store the results in calling object elements.

#	Name	Type	Description
1	Src	TMtxVec *

Remarks:

Size and Vector::Complex property of calling object are adjusted automatically.

Declared in Dew::Math::Vector · Dew.Math/MtxExpr.h · Cross-compiler

Overload 4: void Trunc(DewArray<int> &Dst) const;

Truncate all calling object elements and store the result in the Dst integer array.

#	Name	Type	Description
1	Dst	DewArray<int> &

Remarks:

Length of the array is automatically adjusted. If the calling object is Complex, the length of the Dst array is equal to 2*Vector::Length.

Declared in Dew::Math::Vector · Dew.Math/MtxExpr.h · Cross-compiler

Overload 5: TMtxVec Trunc(TMtxVec Src, int SrcIndex, int Index, int Len) const;

Truncate Src object elements [SrcIndex]..[SrcIndex+Len-1] and store the results to calling object elemenents [Index]..[Index+Len-1].

#	Name	Type	Description
1	Src	TMtxVec *
2	SrcIndex	int
3	Index	int
4	Len	int

Remarks:

Size and Vector::Complex property of calling object must be set explicitly to match those of Src object. An exception is raised if array borders are overrun/underrun.
