Can I store an expression as a double? (or any variable)

This is a super simple question, but it has me confused.

#include <iostream>

using std::cout;
using std::endl;

int main()
{
     double percentage = (3/100);
     
     cout << percentage << endl;
}

Why does this output zero? I was under the impression that expressions could be stored in variables...

Unclose this question! – c0d3r Apr 03 '21 at 20:10
`3/100` int division = `0` `double percentage = 0` – hare1039 Apr 03 '21 at 20:14
@c0d3r May I ask why? The linked target addresses the OPs question as far as I can tell. – cigien Apr 03 '21 at 20:34
@cigien it's this guy's first question. – c0d3r Apr 03 '21 at 20:39
@c0d3r That may be the case, but that is not sufficient reason to reopen a question that was validly closed. – cigien Apr 03 '21 at 20:40
You can't store an expression in a `double`. You can only store the *result* of an expression. – François Andrieux Apr 03 '21 at 22:49
