Implementations

impl BigUint

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

Creates and initializes a BigUint.

The base 2³² digits are ordered least significant digit first.

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

Creates and initializes a BigUint.

The base 2³² digits are ordered least significant digit first.

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

Assign a value to a BigUint.

The base 2³² digits are ordered least significant digit first.

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::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::{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::{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::{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::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::BigUint;

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

pub fn to_u32_digits(&self) -> Vec<u32>

Returns the u32 digits representation of the BigUint ordered least significant digit first.

Examples

use num_bigint::BigUint;

assert_eq!(BigUint::from(1125u32).to_u32_digits(), vec![1125]);
assert_eq!(BigUint::from(4294967295u32).to_u32_digits(), vec![4294967295]);
assert_eq!(BigUint::from(4294967296u64).to_u32_digits(), vec![0, 1]);
assert_eq!(BigUint::from(112500000000u64).to_u32_digits(), vec![830850304, 26]);

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::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::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::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: &Self, modulus: &Self) -> Self

Returns (self ^ exponent) % modulus.

Panics if the modulus is zero.

pub fn cbrt(&self) -> Self

Returns the truncated principal cube root of self – see Roots::cbrt.

pub fn nth_root(&self, n: u32) -> Self

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

impl ToPrimitive for BigUint

fn to_i64(&self) -> Option<i64>

Converts the value of self to an i64. If the value cannot be represented by an i64, then None is returned.

fn to_i128(&self) -> Option<i128>

Converts the value of self to an i128. If the value cannot be represented by an i128 (i64 under the default implementation), then None is returned.

fn to_u64(&self) -> Option<u64>

Converts the value of self to a u64. If the value cannot be represented by a u64, then None is returned.

fn to_u128(&self) -> Option<u128>

fn to_f64(&self) -> Option<f64>

Converts the value of self to an f64. Overflows may map to positive or negative inifinity, otherwise None is returned if the value cannot be represented by an f64.

pub fn to_isize(&self) -> Option<isize>

Converts the value of self to an isize. If the value cannot be represented by an isize, then None is returned.

pub fn to_i8(&self) -> Option<i8>

Converts the value of self to an i8. If the value cannot be represented by an i8, then None is returned.
