struct BigInt
Overview
A BigInt can represent arbitrarily large integers.
It is implemented under the hood with GMP.
Included Modules
- Comparable(UInt16 | UInt32 | UInt64 | UInt8)
- Comparable(Int16 | Int32 | Int64 | Int8)
- Comparable(Float)
- Comparable(BigInt)
Defined in:

Class Method Detail
Creates a BigInt with the value denoted by str in the given base.
Raises ArgumentError if the string doesn't denote a valid integer.
