BigInteger equivalent in Swift?

Question

Is there an equivalent to Java's BigInteger class in Swift? I am tying to do large calculations in Swift with positive integers larger than UInt64 maximum valye.

What is the best way to handle these numbers in Swift?

Answer 1

You can use the NSDecimalNumber class from Cocoa. It is not infinite precision, but it can represent 38 decimal digits of precision, which may be enough for what you need.
