parseNumbers in lib/processors.js does not return right value for floating point numbers such as '3.4028234663853E+038'

[aishwaryapanchal]

<num> <a>-273.17001342773</a> <b>3.4028234663853E+038</b> <c>10864548</c> <d>-0.637</d> </num>

I parsed the above xml file using the parseNumbers of lib/processors.js which gives the following output:
{ num: { a: -273.17001342773, b: 3, c: 10864548, d: -0.637 } }

The property 'b' shows a value 3 instead of 3.4028234663853E+038.

If I replace lib/processors.js function parseNumbers with the following:

if (!isNaN(value)) {
    if (value % 1 === 0 && parseInt(value) == value) {
        value = parseInt(value, 10);
    } else {
        value = parseFloat(value);
    }
}
return value;

Now I get the right value for 'b',
{ num:
{ a: -273.17001342773,
b: 3.4028234663853e+38,
c: 10864548,
d: -0.637 } }

There's discussion about this here:
peerlibrary/node-xml4js#12

What we really need is a way to provide custom parsers for integer / float numbers, this way one could determine the best way to handle large numbers, like using big.js or similar library. The default parsers would ofc ourse be the current ones.
