column<P>::ge(const P cte) const1 and 2) Returns column-of-bools containing column-wise greater-than comparison between this and rhs columns or between this and cte value.
3 and 4) Returns column-of-bools containing column-wise greater-or-equal comparison between this and rhs columns or between this and cte value.
Example
Code
#include <cpptables/table.hh>
using namespace tables;
using namespace std;
void column_gt_ge()
{
const column<unsigned> c0({ 1, 2, 3, 4 ,5});
const column<unsigned> c1({ 1, 2, 10, 20, 30});
{
const column<bool> r0 = c0.gt(c1); // same as c0 > c1
cout << r0 << "\n";
const column<bool> r1 = c0.ge(c1); // same as c0 >= c1
cout << r1 << "\n";
}
{
const column<bool> r0 = c0.gt(3); // same as c0 > 3
cout << r0 << "\n";
const column<bool> r1 = c0.ge(3); // same as c0 >= 3
cout << r1 << "\n";
}
