Struct number 

pub struct number;

The type of numeric values.

The number type uses two internal representations, or subtypes: integer (64-bit) and float (double-precision). Lua converts between them automatically as needed, and math.type reveals the subtype of a value. Integer literals like 3 create integers; literals with a decimal point or exponent like 3.0 or 1e2 create floats.

print(3 / 2)    --> 1.5      (division always produces a float)
print(3 // 2)   --> 1        (floor division)
print(2^10)     --> 1024.0   (exponentiation produces a float)

Trait Implementations

impl arithmetic for number

fn __add(&self, other: any) -> any

The addition (+) operation.

fn __sub(&self, other: any) -> any

The subtraction (-) operation.

fn __mul(&self, other: any) -> any

The multiplication (*) operation.

fn __div(&self, other: any) -> any

The division (/) operation.

fn __mod(&self, other: any) -> any

The modulo (%) operation.

fn __pow(&self, other: any) -> any

The exponentiation (^) operation.

fn __unm(&self) -> any

The negation (unary -) operation.

fn __idiv(&self, other: any) -> any

The floor division (//) operation.

impl bitwise for number

fn __band(&self, other: any) -> any

The bitwise AND (&) operation.

fn __bor(&self, other: any) -> any

The bitwise OR (|) operation.

fn __bxor(&self, other: any) -> any

The bitwise exclusive OR (~) operation.

fn __bnot(&self) -> any

The bitwise NOT (unary ~) operation.

fn __shl(&self, other: any) -> any

The bitwise left shift (<<) operation.

fn __shr(&self, other: any) -> any

The bitwise right shift (>>) operation.

impl comparison for number

fn __eq(&self, other: any) -> boolean

The equal (==) operation. Only invoked when the values being compared are both tables or both full userdata and they are not primitively equal. The result is always converted to a boolean.

fn __lt(&self, other: any) -> boolean

The less than (<) operation.

fn __le(&self, other: any) -> boolean

The less equal (<=) operation.

impl tostring for number

fn __tostring(&self) -> string

Invoked by tostring() (and therefore by print) to convert the value to a string.

fn __name(&self) -> string

A string naming the type of the value, used in error messages and by tostring when __tostring is absent.
