I used Google and found some references for integer in Java.
But "int" not only does not work, it also prevents reading X and Y
coordinates of the mouse.
What i would like to do:
1) Get X and Y mouse coordinates into a variable that i can do real math on.
So far, i can do math on the values "read" and that result goes into
a "variable" that is useful *only* for display.
If i try "int" in that math, the values are then zero for everything
- even those where i do no calculation.
2) Use the calculated integer values as an index to a table or array.
It is acceptable to use an HTML "table" as the source for the lookup;
W(CalcFromX) and P(CalcFromX) would be the resulting values to be
displayed on the screen somewhere.
Can this be done, and eXactly how?

Sorry but you are looking like Rad Hat in that dark forest - lost any

Shockwave #1
JavaScript is not Java (despite the equal first syllable). Unlike Java
- JavaScript is a loose typed language with current variable type
interpreted based on the current variable value.
Shockwave #2
JavaScript execution environment (where var c = a+b) is completely
separate from DOM (Document Object Model) where say mouse pointer is
hanging out over x120 y220 where element with id "myStuff" happened to
be located.
Truthfully I am not even sure that your problem is within JavaScript -
because it can be interpreted as a misplaced *Java* question.
If it is not, please narrow your problem description to a particular
language with a possible code stamp / URL/

Not quite true. There is an `int' type, and variables can be strictly
typed, in JavaScript 2.0. However, that is not implemented in a
browser
yet.
And as such, even mentioning it is useless other than a waste of
bandwidth and time for anybody who reads it.
Incorrect; the info explained why i had so much trouble.
You had trouble because you were using, or attempting to use, a feature
that is not part of the language. Not because of a feature that might be
in a future release of the language unless you were reading a draft copy
of JavaScript2.0 in which case you should have known it wasn't in use yet.
I had no idea that the "int" "feature" was not a part of the language.
I consider that short-sighted at best and ignorantly stupid.
All languages i have seen or heard of that pretend to do some math
*have* either different numeric variable types, or type conversion
(almost always both).
And that has been the case before the PCs came out (1980)!
Draft copy? You mean that there is some kind of (?readable and
understandable? ) document that covers Java?
Would such a thing help me?

It seems i am using Java Script, inside HTML code in an attempt to do

If anyone has used Excel to create a chart, and then "visits" a dot
or point on that chart, a yellow box shows up giving the value of that

*That* is what i want to do, or an equivalent.

AFAIK, it is merely not part of a language version that is implemented _in
Web browsers_. You could have RTFM first, and even if you had not, you

You should reconsider that. The dynamic nature of J(ava)Script versions,
and other implementations of ECMAScript Editions 1 to 3, made it possible
that they became such widely supported languages.

All languages i have seen or heard of that pretend to do some math
*have* either different numeric variable types, or type conversion
(almost always both).
J(ava)Script implemented client-side *has* type conversion, both explicit
and implicit.
And that has been the case before the PCs came out (1980)!

If you would develop using a language that implements it, such as

There are browsers that follow standards much more closely and fully than
