To create arbitrary BigInts via the C++ API, use BigInt::NewFromWords. An alternative, as you suggest, is to parse the string as source, because "BigInt strings with 'n' suffixes" are BigInt literals. Instead of "eval", the API functions to do that are Script::Compile and Script::Run. Look at samples/shell.cc or test/cctest/* for examples.
Another alternative, depending on your requirements, might be to create this custom "parser" (more of a wrapper, really) in JavaScript: function MyBigInt(str) { console.assert(str.endsWith("n")); return BigInt(str.substring(0, str.length - 1)); } On Sat, Sep 15, 2018 at 8:44 PM J Decker <d3c...@gmail.com> wrote: > > > On Sat, Sep 15, 2018 at 8:41 PM J Decker <d3c...@gmail.com> wrote: > >> I was implementing a parser that includes BigInt strings with 'n' >> suffixes... >> I tried to create a BigInt::New( isolate, ... and then found the only >> constructor takes an int64; which isn't a very big int. >> >> howto bigint from string? >> > > maybe someone could share a snippet to call eval()?
