Crate hyperoperator

Expand description

hyperoperator-rs is a crate that supports different types of hyperoperations (hyper exponention, hyper root (super root) and hyper log (super log)). If you don’t know about hyperoperations then see the article: Hyperoperation.

What can this library do

  • Computes tetration, pentation, hextation and etc.
  • Computes super roots and super log (only hyper natural logarithm, other hyper logarithms can only be computed only approximately)
  • Supports BigUint and BigFloat types for calculations

Example

Hyper exponention

use num_bigfloat::BigFloat;
use hyperoperator::pow::HyperPow;

let a = BigFloat::parse("2.4").unwrap();
let b = BigFloat::parse("2.6").unwrap();
// tetration
assert_eq!(a.hyperpow(b, 2).to_string(), "1.042500508439915903472643420925599720010e+2");

Hyper (super) root

use num_bigfloat::BigFloat;
use hyperoperator::root::HyperRoot;

let a = BigFloat::parse("27.0").unwrap();
let b = BigFloat::from_f64(std::f64::consts::E);
// tetration
assert_eq!(a.hypersqrt(2).to_string(), "3.000000000000000000000000000000000000000");
assert_eq!(b.hypersqrt(2).to_string(), "1.763222834351896654975492603088735114643");

Hyper (super) log

use num_bigfloat::BigFloat;
use hyperoperator::log::HyperLog;

let a = BigFloat::parse("1.2").unwrap();
// tetration
assert_eq!(a.hyperln(2).to_string(), "1.435727851007358140921528061434015461824e-2");
