Implementations

impl BigUint

pub fn new(digits: Vec<u32>) -> BigUint

Creates and initializes a BigUint.

The digits are in little-endian base 2³².

pub fn new_native(digits: SmallVec<[u64; 4]>) -> BigUint

Creates and initializes a BigUint.

The digits are in little-endian base matching BigDigit.

pub fn from_slice(slice: &[u32]) -> BigUint

Creates and initializes a BigUint.

The digits are in little-endian base 2³².

pub fn from_slice_native(slice: &[u64]) -> BigUint

Creates and initializes a BigUint.

The digits are in little-endian base matching BigDigit

pub fn get_limb(&self, i: usize) -> u64

pub fn assign_from_slice(&mut self, slice: &[u32])

Available on crate feature u64_digit only.

pub fn assign_from_slice_native(&mut self, slice: &[u64])

Assign a value to a BigUint.

The digits are in little-endian with the base matching BigDigit.

pub fn from_bytes_be(bytes: &[u8]) -> BigUint

Creates and initializes a BigUint.

The bytes are in big-endian byte order.

Examples

use num_bigint_dig::BigUint;

assert_eq!(BigUint::from_bytes_be(b"A"),
           BigUint::parse_bytes(b"65", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"AA"),
           BigUint::parse_bytes(b"16705", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"AB"),
           BigUint::parse_bytes(b"16706", 10).unwrap());
assert_eq!(BigUint::from_bytes_be(b"Hello world!"),
           BigUint::parse_bytes(b"22405534230753963835153736737", 10).unwrap());

pub fn from_bytes_le(bytes: &[u8]) -> BigUint

Creates and initializes a BigUint.

The bytes are in little-endian byte order.

pub fn parse_bytes(buf: &[u8], radix: u32) -> Option<BigUint>

Creates and initializes a BigUint. The input slice must contain ascii/utf8 characters in [0-9a-zA-Z]. radix must be in the range 2...36.

The function from_str_radix from the Num trait provides the same logic for &str buffers.

Examples

use num_bigint_dig::{BigUint, ToBigUint};

assert_eq!(BigUint::parse_bytes(b"1234", 10), ToBigUint::to_biguint(&1234));
assert_eq!(BigUint::parse_bytes(b"ABCD", 16), ToBigUint::to_biguint(&0xABCD));
assert_eq!(BigUint::parse_bytes(b"G", 16), None);

pub fn from_radix_be(buf: &[u8], radix: u32) -> Option<BigUint>

Creates and initializes a BigUint. Each u8 of the input slice is interpreted as one digit of the number and must therefore be less than radix.

The bytes are in big-endian byte order. radix must be in the range 2...256.

Examples

use num_bigint_dig::{BigUint};

let inbase190 = &[15, 33, 125, 12, 14];
let a = BigUint::from_radix_be(inbase190, 190).unwrap();
assert_eq!(a.to_radix_be(190), inbase190);

pub fn from_radix_le(buf: &[u8], radix: u32) -> Option<BigUint>

Creates and initializes a BigUint. Each u8 of the input slice is interpreted as one digit of the number and must therefore be less than radix.

The bytes are in little-endian byte order. radix must be in the range 2...256.

Examples

use num_bigint_dig::{BigUint};

let inbase190 = &[14, 12, 125, 33, 15];
let a = BigUint::from_radix_be(inbase190, 190).unwrap();
assert_eq!(a.to_radix_be(190), inbase190);

pub fn to_bytes_be(&self) -> Vec<u8>

Returns the byte representation of the BigUint in big-endian byte order.

Examples

use num_bigint_dig::BigUint;

let i = BigUint::parse_bytes(b"1125", 10).unwrap();
assert_eq!(i.to_bytes_be(), vec![4, 101]);

pub fn to_bytes_le(&self) -> Vec<u8>

Returns the byte representation of the BigUint in little-endian byte order.

Examples

use num_bigint_dig::BigUint;

let i = BigUint::parse_bytes(b"1125", 10).unwrap();
assert_eq!(i.to_bytes_le(), vec![101, 4]);

pub fn to_str_radix(&self, radix: u32) -> String

Returns the integer formatted as a string in the given radix. radix must be in the range 2...36.

Examples

use num_bigint_dig::BigUint;

let i = BigUint::parse_bytes(b"ff", 16).unwrap();
assert_eq!(i.to_str_radix(16), "ff");

pub fn to_radix_be(&self, radix: u32) -> Vec<u8>

Returns the integer in the requested base in big-endian digit order. The output is not given in a human readable alphabet but as a zero based u8 number. radix must be in the range 2...256.

Examples

use num_bigint_dig::BigUint;

assert_eq!(BigUint::from(0xFFFFu64).to_radix_be(159),
           vec![2, 94, 27]);
// 0xFFFF = 65535 = 2*(159^2) + 94*159 + 27

pub fn to_radix_le(&self, radix: u32) -> Vec<u8>

Returns the integer in the requested base in little-endian digit order. The output is not given in a human readable alphabet but as a zero based u8 number. radix must be in the range 2...256.

Examples

use num_bigint_dig::BigUint;

assert_eq!(BigUint::from(0xFFFFu64).to_radix_le(159),
           vec![27, 94, 2]);
// 0xFFFF = 65535 = 27 + 94*159 + 2*(159^2)

pub fn bits(&self) -> usize

Determines the fewest bits necessary to express the BigUint.

pub fn modpow(&self, exponent: &BigUint, modulus: &BigUint) -> BigUint

Panics if the modulus is zero.

Returns the truncated principal nth root of self – see Roots::nth_root.

pub fn trailing_zeros(&self) -> Option<usize>

pub fn set_digit(&mut self, digit: u64)

Sets the value to the provided digit, reusing internal storage.
