A one-argument builtin.

Variants

Sin

EEL2’s sin — radians.

Cos

EEL2’s cos — radians.

Tan

EEL2’s tan — radians.

Asin

EEL2’s asin, on an argument clamped into -1..=1.

Acos

EEL2’s acos, on an argument clamped into -1..=1.

Atan

EEL2’s atan.

Sqrt

EEL2’s sqrt, 0 on a negative argument.

InvSqrt

1 / sqrt(x), EEL2’s invsqrt.

Exp

EEL2’s exp.

Log

Natural log, EEL2’s log.

Log10

Base-10 logarithm, EEL2’s log10.

Abs

EEL2’s abs.

Sign

EEL2’s three-way sign: -1, 0 or 1.

Sqr

x * x, EEL2’s sqr.

Floor

EEL2’s floor.

Ceil

EEL2’s ceil.

Int

Truncation toward zero, EEL2’s int.

BNot

EEL2’s bnot: 1 when the argument is zero, else 0.

Rand

rand(x) — a salted deterministic draw in [0, x) (ADR-0051).

RandInt

randint(x) — floor(rand(x)).

Implementations

impl Unary

pub fn as_str(self) -> &'static str

The name the assembly text uses, which is also the EEL2 spelling.

pub fn from_name(name: &str) -> Option<Self>

Parse an assembly/EEL2 name.

pub fn is_random(self) -> bool

Whether this builtin reads the VM’s RNG rather than only its argument. The two that do are the reason a program’s execution is a function of (inputs, salt, call sequence) rather than of the inputs alone.

Trait Implementations

impl Clone for Unary

fn clone(&self) -> Unary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Unary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Unary

fn eq(&self, other: &Unary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Unary

impl Eq for Unary

impl StructuralPartialEq for Unary
