Implementations

impl JsBigInt

pub fn new<T: Into<Self>>(value: T) -> Self

Create a new JsBigInt.

pub fn zero() -> Self

Create a JsBigInt with value 0.

pub fn is_zero(&self) -> bool

Check if is zero.

pub fn one() -> Self

Create a JsBigInt with value 1.

pub fn is_one(&self) -> bool

Check if is one.

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

Convert bigint to string with radix.

pub fn to_f64(&self) -> f64

Converts the BigInt to a f64 type.

Returns f64::INFINITY if the BigInt is too big.

pub fn from_string_radix(buf: &str, radix: u32) -> Option<Self>

Converts a string to a BigInt with the specified radix.

pub fn from_string(string: &str) -> Option<Self>

This function takes a string and conversts it to BigInt type.

pub fn same_value_zero(x: &Self, y: &Self) -> bool

Checks for SameValueZero equality.

pub fn same_value(x: &Self, y: &Self) -> bool

Checks for SameValue equality.

pub fn equal(x: &Self, y: &Self) -> bool

Checks for mathematical equality.

The abstract operation BigInt::equal takes arguments x (a BigInt) and y (a BigInt). It returns true if x and y have the same mathematical integer value and false otherwise.
