Open xcaptain opened 2 weeks ago

xcaptain commented 2 weeks ago

For example: 99999999999999999999999999*888888888888888888888888888888888888888

is a simple expression but will throw an Exception when eval it.

BigInteger will be supported by Parlot parser in the upcoming release, then we can implement it's support in NCalc

Thanks, related to This PR right? I saw BigInteger in tests.

Bykiev commented 2 weeks ago

Yes. you're right

I tried the new Parlot version in my local dev env, the BigInteger worked, hope to see a new version soon. Also I think as a math calculator, it's no need to handle overflow, because integer space is infinite, convert to BigInteger is more useful.

The integer overflow can be useful in some cases. BigInteger support can be added via ExpressionOptions without any breaking changes.
