Hi,
I have designed a Javascript extension which supports big integers, big
floats and operator overloading. It is not 100% compatible with
Javascript because I wanted no distinction between legacy javascript
numbers and big integers or big floats, but most of the language
semantics are preserved. I guess some ideas may be useful for a 100%
compatible behavior, in particular for the operator overloading.
I published a summary of the changes at http://numcalc.com/jsbignum.pdf
. A preliminary implementation running a numerical calculator is
available at http://numcalc.com . The source code of the calculator (
http://numcalc.com/jscalc.js ) shows how the bignum extensions can be
used to easily manipulate fractions, complex numbers, polynomials and
matrixes.
Fabrice.
