I have an object storing integers, many formulas may of course generate the same integer. And for some expressions for example on form a*x^j i would like to store each occurence. Now all my numbers are printed out in a square grid.

Right now the storing structure look like this and i set fontcolor and rectangle color as i print out the grid.

However i would like to store multiple func and rcolors within same object?
Thus make func and rcolor the multidimensional part of the array.

I am totally clueless for how both initiate and update such an object in javascript. I have managed to do it for numbers but i never initiated the object it was somehow forked in as i updated the object. And i really did not understand how it really worked. So if someone could show me howto make this array of integers to holld multiple functions and rectangles for each arr[i] it would be great.

function arraysize()
{

for ( i = - scope; i <= scope; i ++ )
{
arr[i] =
{
count : i,
func : '',
fcolor : 'black',
rheight : 100,
rwidth : 100,
rcolor : 'white',
prime : true,
formula : 0,
sigma : 0,
}
}
}

Lets hope you sobered up...
var x = new Array(10);
for (var i = 0; i < 10; i++) {
x[i] = new Array(20);
}
x[5][12] = 3.0;

How does this relate to my example array above?
I do not know how many occurences there will be, and it is only the func and rcolor property of the object that will be multidimensional.

for ( i = - scope; i <= scope; i ++ )
{

arr[i] =
{
count : i,
func : '',
fcolor : 'black',
rheight : 100,
rwidth : 100,
rcolor : 'white',
prime : true,
formula : 0,
sigma : 0,
}
arr[i] = new Array(20);//??????????
}
}

If i let out 20 above, arr[i] = new Array(); will the subarray dynamically assign memory as i pass new properties?

So to update the object i use arr[x][y].func="mystring" or arr[x][y].rcolor="green".

Is there space allocated for the rest of the attributes/properties of the object?

Does the object creation and the update seem right?

Don't. It's going to be slower.

Well just storing them within the array can hardly slow it down or?

Memoization isn't free and your approach would be even less so. I've written a little about this topic in the past:

For even greater justice, but a tad slower using base 10 but faster and bigger using bigger base.
