Fields

__private_field: ()

Methods from Deref<Target = BigUint>

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

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

Returns (self ^ exponent) % modulus.

Panics if the modulus is zero.

pub fn sqrt(&self) -> Self

Returns the truncated principal square root of self – see Roots::sqrt

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.

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