Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TMtxVec *Floor() const; | Rounds towards negative infinity. |
| 2 | TMtxVec *Floor(int Index, int Len) const; | Rounds calling object elements [Index]..[Index+Len-1] towards negative infinity in-place. |
| 3 | TMtxVec *Floor(TMtxVec *Src) const; | Rounds all Src object elements towards negative infinity. |
| 4 | TMtxVec *Floor(TMtxVec *Src, int SrcIndex, int Index, int Len) const; | Rounds Src object elements [SrcIndex]..[SrcIndex+Len-1] towards negative infinity- |
Overload 1: TMtxVec *Floor() const;
Rounds towards negative infinity.
Remarks:
Rounds all calling object elements towards negative infinity in-place.
Floor(-2.8) = -3 Floor(2.8) = 2 Floor(-1.0) = -1
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
a.SetIt(DewArray<double>{ 1.2, 2.7, -0.5, 3.9 });
a.Floor();
Vector expected;
expected.SetIt(DewArray<double>{ 1.0, 2.0, -1.0, 3.0 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
throw tException("Vector.Floor: mismatch");
}Declared in Dew::Math::Vector · Dew.Math/MtxExpr.h · Cross-compiler
Overload 2: TMtxVec *Floor(int Index, int Len) const;
Rounds calling object elements [Index]..[Index+Len-1] towards negative infinity in-place.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | int | |
| 2 | Len | int |
Remarks:
An exception is raised if array borders are overrun.

Overload 3: TMtxVec *Floor(TMtxVec *Src) const;
Rounds all Src object elements towards negative infinity.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TMtxVec * |
Remarks:
Stores the result in the calling object. Size and Vector::Complex properties of the calling object are adjusted automatically.
Examples

#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
Vector x;
x.SetIt(DewArray<double>{ 1.2, 2.7, -0.5, 3.9 });
a.Floor(x);
Vector expected;
expected.SetIt(DewArray<double>{ 1.0, 2.0, -1.0, 3.0 });

Overload 4: TMtxVec *Floor(TMtxVec *Src, int SrcIndex, int Index, int Len) const;
Rounds Src object elements [SrcIndex]..[SrcIndex+Len-1] towards negative infinity-
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TMtxVec * | |
| 2 | SrcIndex | int | |
| 3 | Index | int | |
| 4 | Len | int |
Remarks:
Store the result in the calling object elements [Index]..[Index+Len-1] Size and Vector::Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
