Description

Count the number of occurances of the elements in the input vector that are satisfied with the comparison condition.

Syntax

int ocmath_count( double dValue, uint nPts, const double * pIn, int nCondition = COUNT_EQUAL )

Parameters

dValue: [input] the double value for comparison.
nPts: [input] the size of input array.
pIn: [input] input array.
nCondition: [input] comparison condition.; COUNT_GREATER_EQUAL,//greater than or equal(>=); COUNT_GREATER,//greater than(>); COUNT_LESS_EQUAL,//less than or equal(<=); COUNT_LESS,//less than(<); COUNT_EQUAL,//equal(==); COUNT_UNEQUAL //unequal(!=)

Return

The function returns the number of values found in the given array.

Examples

EX1

void ocmath_count_ex1()
{
    Worksheet wks = Project.ActiveLayer();
    wks.SetSize(-1,2);
    DataRange dr;
    dr.Add("X", wks, 0, 0, -1, 0);
    dr.Add("X", wks, 0, 1, -1, 1);
    vector vIn;
    dr.GetData(&vIn, 1);
    double dbMin, dbMax;
    vIn.GetMinMax(dbMin, dbMax);
    double dValue = (dbMin+dbMax)/2;
    int num=ocmath_count(dValue, vIn.GetSize(),vIn, COUNT_LESS);
}
