Class Method Detail

def self.new(str : String, base = 10)Source

Creates a BigInt with the value denoted by str in the given base.

Raises ArgumentError if the string doesn't denote a valid integer.

BigInt.new("123456789123456789123456789123456789") # => 123456789123456789123456789123456789
BigInt.new("1234567890ABCDEF", base: 16)           # => 1311768467294899695

def self.new(num : Int::Signed)Source

Creates a BigInt from the given num.

def self.new(num : Int::Unsigned)Source

Creates a BigInt from the given num.

def self.new(num : Float)Source

Creates a BigInt from the given num.

def self.new(num : BigInt)Source

Returns num. Useful for generic code that does T.new(...) with T being a Number-

def self.newSource

Creates a BigInt with the value zero.

require "big"
BigInt.new # => 0
