Package Exports

node-biginteger
node-biginteger/lib/common

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-biginteger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-biginteger

This library is based on java.math.BigInteger Dependency Long

example

  $ npm install node-biginteger

  var BigInteger = require('node-biginteger');
  var n = BigInteger.fromString('abc', 16);
  n.toString(16);
