Struct yksom::vm::objects::ArbInt

pub struct ArbInt { /* fields omitted */ }

A boxed arbitrary sized BigInt.

Implementations

impl ArbInt

pub fn new(vm: &mut VM, val: BigInt) -> Val

Create a Val representing the BigInt integer val. Note that this will create the most efficient integer representation that can represent val (i.e. this might create a tagged isize, a boxed isize, or a boxed BigInt) – the VM relies, in various places, on this property (e.g. an ArbInt with a value 1 would cause odd errors elsewhere).

pub fn bigint(&self) -> &BigInt

pub fn to_f64(&self, vm: &VM) -> Result<f64, Box<VMError>>

If this ArbInt can be represented as a finite f64, return that value; otherwise return Err(CantRepresentAsDouble).
