Hi sarapham40...
Remember 'bash' has only integer arithmetic and can only go to a maximum and minimum whole number integer values depending on whether the OS is 32bit or 64bit.
Square root is not possible in PURE bash as it does not have the ability of floating point maths.
You do have tools at your disposal to get the square roots, (awk, bc, python, perl and others), and drop the results into variables or redirect to files.
If you use 'ksh' as the shell this has excellent builtin floating point maths so you could create your SQRT() function using Newton's method and then the whole would be a PURE shell script.
Alternatively you could use pseudocode x**(1.0/2.0) as your square root too.
Just hints to help on the way...

I need your help to discover missing elements for each box.
In theory each box should have 4 items: ITEM01, ITEM02, ITEM08, and ITEM10.
Some boxes either have a missing item (BOX02 ITEM08) or might have da duplicate item (BOX03 ITEM02) and missing another one (BOX03 ITEM01).

LEARN ABOUT PHP
array_merge_recursive
ARRAY_MERGE_RECURSIVE(3) 1 ARRAY_MERGE_RECURSIVE(3)
array_merge_recursive - Merge two or more arrays recursively
SYNOPSIS
array array_merge_recursive (array $array1, [array $...])
DESCRIPTION
array_merge_recursive(3) merges the elements of one or more arrays together so that the values of one are appended to the end of the previ-
ous one. It returns the resulting array.
If the input arrays have the same string keys, then the values for these keys are merged together into an array, and this is done recur-
sively, so that if one of the values is an array itself, the function will merge it with a corresponding entry in another array too. If,
however, the arrays have the same numeric key, the later value will not overwrite the original value, but will be appended.
PARAMETERS
o $array1
- Initial array to merge.
o $...
- Variable list of arrays to recursively merge.
RETURN VALUES
An array of values resulted from merging the arguments together.
EXAMPLES
Example #1
array_merge_recursive(3) example
<?php
$ar1 = array("color" => array("favorite" => "red"), 5);
$ar2 = array(10, "color" => array("favorite" => "green", "blue"));
$result = array_merge_recursive($ar1, $ar2);
print_r($result);
?>
The above example will output:
Array
(
[color] => Array
(
[favorite] => Array
(
[0] => red
[1] => green
)
[0] => blue
)
[0] => 5
[1] => 10
)
