+    # RustBigInt
+    BigInt written in Rust.
+    ## Description
+    My own implementation of BigInt (type of integer with unlimited size) as project to learn Rust.
+    ## Example
+    ```rs
+    use RustBigInt::BigInt;
+    use std::str::FromStr;
+    //from
+    let x: BigInt = 66.into();
+    let y: BigInt = BigInt::from(34);
+    let z: BigInt = BigInt::from_str("999999").unwrap();
+    //tryInto
+    let x: BigInt = 32.into();
+    let x_num: i32 = x.try_into.unwrap();
+    assert_eq!(32, x_num);
+    let y: BigInt = i16:MAX.into();
+    let y_num: i8 = y.try_into();
+    assert!(y_num.is_err());
+    //Display
+    let x: BigInt = BigInt::from(1003);
+    assert_eq!(format!("Number is: {x}"), "Number is: 1003");
+    assert_eq!(format!("Number is: {x:0^11}"), "Number is: 00010030000");
+    assert_eq!(format!("Number is: {x:0>10}"), "Number is: 0000001003");
+    assert_eq!(format!("Number is: {x:0<10}"), "Number is: 1003000000");
+    assert_eq!(format!("Number is: {x:->10}"), "Number is: ------1003");
+    assert_eq!(format!("Number is: {x:9}"), "Number is:      1003");
+    //Binary
+    let x: BigInt = BigInt::from(11);
+    assert_eq!(format!("{x:#b}"), "0b1011");
+    assert_eq!(format!("{x:b}"), "1011");
+    assert_eq!(format!("{x:0^11b}"), "00010110000");
+    //Hexadecimal
+    let x: BigInt = BigInt::from(11);
+    assert_eq!(format!("{x:x}"), "a");
+    assert_eq!(format!("{x:X}"), "A");
+    assert_eq!(format!("{x:#X}"), "0xA");
+    assert_eq!(format!("{x:0^11X}"), "00000A00000");
+    let x: BigInt = BigInt::from(20);
+    assert_eq!(x.to_words(), "two zero");
+    //Math operations
+    let x: BigInt = BigInt::from(66);
+    let y: BigInt = BigInt::from(34);
+    assert!(x != y);
+    assert_eq!(x + y, 100);
+    assert_eq!(x - y, 32);
+    assert_eq!(x * y, 2244);
+    assert_eq!(x / y, 1);
+    assert_eq!(x % y, 32);
+    assert_eq!(x.pow(2), 4356);
+    //Binary operations
+    let x: BigInt = 11; //Ob1011
+    let y: BigInt = 6; //Ob0110
+    assert_eq!(x & y, 2); //0b0010
+    assert_eq!(x | y, 15); //0b1111
+    assert_eq!(x ^ y, 13); //0b1101
+    assert_eq!(x >> 2, 2) //0b10
+    assert_eq!(x << 2, 44) //0b101100
