Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TMtxVec *Frac() const; | Fractional part of values. |
| 2 | TMtxVec *Frac(TMtxVec *X) const; | Calculates the fractional part for all X object values and stores the result in calling object. |
| 3 | TMtxVec *Frac(int Index, int Len) const; | Calculates the fractional part for calling object elements [Index]..[Index+Len-1] in-place |
| 4 | TMtxVec *Frac(TMtxVec *X, int XIndex, int Index, int Len) const; | Calculates the fractional part for X object elements [XIndex]..[XIndex+Len-1] and stores the result in calling object elements [Index]..[Index+Len-1]. |
Overload 1: TMtxVec *Frac() const;
Fractional part of values.
Remarks:
Calculates the fractional part for all object values in-place.
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Matrix a;
a.SetIt(2, 2, false, DewArray<double>{ 1.2, 2.7, -0.5, 3.9 });
a.Frac();
Matrix expected;
expected.SetIt(2, 2, false, DewArray<double>{ 0.2, 0.7, -0.5, 0.9 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
throw tException("Matrix.Frac: mismatch");
}#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Matrix a;
int ind;
a.SetIt(2, 2, false, DewArray<double>{1, 5.5, -1.6, 6}); // a = [1, 5.5, -1.6, 6]
a.Frac(); // a = [0, 0.5, -0.6, 0]
