Huge Integer JavaScript Library

Question

Is there any JavaScript library that can be used for calculations involving 700+ Digits? Also, how about the same thing in C++?

Answer 1

JavaScript:

• Leemon Baird's BigInt library. This seems to be popular. It's made specifically for cryptographic uses.
• My own BigInteger library. Similar to the Java BigInteger class, but all calculations are done in base-10.
• jsbn. Another BigInteger class similar to Java's. I've never used this one, but the API looks similar to mine.

C++:

• Most people use GMP.
• CLN - Class Library for Numbers. I've used this in the past and it has a pretty nice API.

Answer 2

For JS: How about BigInt?

For C++: Google found me this.

Answer 3

For C++ GMP has served me very well in the past for large numbers, it claims to be the fastest bignum library out there too, which is bound to be helpful for 700 digits.
