Struct bert::BertBigInteger

pub struct BertBigInteger(pub BigInt);

Methods from Deref<Target = BigInt>

fn to_bytes_le(&self) -> (Sign, Vec<u8>)

Returns the sign and the byte representation of the BigInt in little-endian byte order.

Examples

use num_bigint::{ToBigInt, Sign};

let i = -1125.to_bigint().unwrap();
assert_eq!(i.to_bytes_le(), (Sign::Minus, vec![101, 4]));

fn to_bytes_be(&self) -> (Sign, Vec<u8>)

Returns the sign and the byte representation of the BigInt in big-endian byte order.

Examples

use num_bigint::{ToBigInt, Sign};

let i = -1125.to_bigint().unwrap();
assert_eq!(i.to_bytes_be(), (Sign::Minus, vec![4, 101]));

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::BigInt;

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

fn sign(&self) -> Sign

Returns the sign of the BigInt as a Sign.

Examples

use num_bigint::{ToBigInt, Sign};

assert_eq!(ToBigInt::to_bigint(&1234).unwrap().sign(), Sign::Plus);
assert_eq!(ToBigInt::to_bigint(&-4321).unwrap().sign(), Sign::Minus);
assert_eq!(ToBigInt::to_bigint(&0).unwrap().sign(), Sign::NoSign);

fn bits(&self) -> usize

Determines the fewest bits necessary to express the BigInt, not including the sign.

fn to_biguint(&self) -> Option<BigUint>

Converts this BigInt into a BigUint, if it's not negative.

fn checked_add(&self, v: &BigInt) -> Option<BigInt>

fn checked_sub(&self, v: &BigInt) -> Option<BigInt>

fn checked_mul(&self, v: &BigInt) -> Option<BigInt>

fn checked_div(&self, v: &BigInt) -> Option<BigInt>
