Julia: Represent Big integers

Julia provide BigInt(x) method to create an arbitrary precision integer.

julia> data=BigInt(123456789876543212345678987654321123456)
123456789876543212345678987654321123456

julia> data=data+1
123456789876543212345678987654321123457

julia> data=data+123456
123456789876543212345678987654321246913

julia> typeof(data)
BigInt

Convert string to BigInt

By using parse method a string can be converted to BigInt.

parse(type, str[, base])

Argument	Description
type	Represents the type to convert. Default base is 10.
str	String to convert. If string is not valid number, then error is raised.
base	Base is optional, for integer conversion default to 10.

julia> parse(BigInt,"123456789876543212345678987654321123456")
123456789876543212345678987654321123456

julia> parse(BigInt,"123456789876543212345678987654321123456",16)
6495562832392744988215426867090392857409893462

Convert String literal to BigInt

By using big string literal form, you can convert a string literal to BigInt.

julia> x=big"100123456789876543212345678987654321123456"
100123456789876543212345678987654321123456

julia> typeof(x)
BigInt
