By reviewing this and this, I've come up with a function, that's probably more complex than it should be, but, man, my math sux:
function tablize(elements)
{
var root = Math.floor(Math.sqrt(elements));
var factors = [];
for (var i = 1; i <= root; i++)
{
if (elements % i === 0)
{
factors.push([i, elements / i]);
}
}
var smallest = null;
for (var f = 0; f < factors.length; f++)
{
var factor = factors[f];
var current = Math.abs(factor[0] - factor[1]);
if (!smallest || factors[smallest] > factor)
{
smallest = f;
}
}
return factors[smallest];
}
While this does work, it provides results I'm not satisfied with.
For instance - 7, it's divided in 1x7, where I'd like it to be 3x3. That's the minimum, optimal, grid size needed to fill with 7 elements.
Also - 3, it's divided in 1x3, where I'd like it to be 2x2.
I need this for a live camera feed frame distribution on a monitor, but I'm totally lost. The only way I can think of is building an extra function to feed with previously generated number and divide again, but that seems wrong.
What is the optimal solution to solve this?
