BigInt
.. BigInt(x)
Create an arbitrary precision integer. ``x`` may be an ``Int`` (or anything
that can be converted to an ``Int``). The usual mathematical operators are
defined for this type, and results are promoted to a ``BigInt``.
Instances can be constructed from strings via :func:`parse`, or using the
``big`` string literal.
Examples
In the Julia programming language, the BigInt(x)
function is used to create arbitrary precision integers. The argument x
can be an Int
or anything that can be converted to an Int
. The usual mathematical operators are defined for this type, and results are automatically promoted to BigInt
.
Here are some examples of using the BigInt
function:

Create a
BigInt
from anInt
:julia> a = BigInt(10) 10
In this example, we create a
BigInt
with the value 10 from anInt
. 
Perform arithmetic operations with
BigInt
:julia> a = BigInt(10) 10 julia> b = BigInt(5) 5 julia> c = a + b 15
Here, we perform addition on two
BigInt
numbersa
andb
, and store the result inc
. 
Create a
BigInt
from a string usingparse
:julia> str = "12345678901234567890" "12345678901234567890" julia> a = parse(BigInt, str) 12345678901234567890
This example demonstrates how to create a
BigInt
from a string using theparse
function.  Create a
BigInt
using thebig
string literal:julia> a = big"12345678901234567890" 12345678901234567890
In this example, we use the
big
string literal to create aBigInt
directly from a string.
Please note that the BigInt
function is used to create arbitrary precision integers, which allow for calculations with extremely large numbers that may exceed the range of regular Int
types.
