#[repr(transparent)]pub struct Number { /* fields omitted */ }

Implementations

impl Number[src]

pub fn is_finite(value: &JsValue) -> bool[src]

The Number.isFinite() method determines whether the passed value is a finite number.

MDN documentation

impl Number[src]

pub fn is_integer(value: &JsValue) -> bool[src]

The Number.isInteger() method determines whether the passed value is an integer.

MDN documentation

impl Number[src]

pub fn is_nan(value: &JsValue) -> bool[src]

The Number.isNaN() method determines whether the passed value is NaN and its type is Number. It is a more robust version of the original, global isNaN().

MDN documentation

impl Number[src]

pub fn is_safe_integer(value: &JsValue) -> bool[src]

The Number.isSafeInteger() method determines whether the provided value is a number that is a safe integer.

MDN documentation

impl Number[src]

pub fn new(value: &JsValue) -> Number[src]

👎 Deprecated:

recommended to use Number::from instead

The Number JavaScript object is a wrapper object allowing you to work with numerical values. A Number object is created using the Number() constructor.

MDN documentation

impl Number[src]

pub fn parse_int(text: &str, radix: u8) -> f64[src]

The Number.parseInt() method parses a string argument and returns an integer of the specified radix or base.

MDN documentation

impl Number[src]

pub fn parse_float(text: &str) -> f64[src]

The Number.parseFloat() method parses a string argument and returns a floating point number.

MDN documentation

impl Number[src]

pub fn to_locale_string(&self, locale: &str) -> JsString[src]

The toLocaleString() method returns a string with a language sensitive representation of this number.

MDN documentation

impl Number[src]

pub fn to_precision(&self, precision: u8) -> Result<JsString, JsValue>[src]

The toPrecision() method returns a string representing the Number object to the specified precision.

MDN documentation

impl Number[src]

pub fn to_fixed(&self, digits: u8) -> Result<JsString, JsValue>[src]

The toFixed() method returns a string representing the Number object using fixed-point notation.

MDN documentation

impl Number[src]

pub fn to_exponential(&self, fraction_digits: u8) -> Result<JsString, JsValue>[src]

The toExponential() method returns a string representing the Number object in exponential notation.

MDN documentation

impl Number[src]

pub fn to_string(&self, radix: u8) -> Result<JsString, JsValue>[src]

The toString() method returns a string representing the specified Number object.

MDN documentation

impl Number[src]

pub fn value_of(&self) -> f64[src]

The valueOf() method returns the wrapped primitive value of a Number object.

MDN documentation

impl Number[src]

pub const EPSILON: f64[src]

The smallest interval between two representable numbers.

MDN Documentation

pub const MAX_SAFE_INTEGER: f64[src]

The maximum safe integer in JavaScript (2^53 - 1).

MDN Documentation

pub const MAX_VALUE: f64[src]

The largest positive representable number.

MDN Documentation

pub const MIN_SAFE_INTEGER: f64[src]

The minimum safe integer in JavaScript (-(2^53 - 1)).

MDN Documentation

pub const MIN_VALUE: f64[src]

The smallest positive representable number—that is, the positive number closest to zero (without actually being zero).

MDN Documentation

pub const NAN: f64[src]

Special "Not a Number" value.

MDN Documentation

pub const NEGATIVE_INFINITY: f64[src]

Special value representing negative infinity. Returned on overflow.

MDN Documentation

pub const POSITIVE_INFINITY: f64[src]

Special value representing infinity. Returned on overflow.

Methods from Deref<Target = Object>

pub fn constructor(&self) -> Function[src]

The constructor property returns a reference to the Object constructor function that created the instance object.

MDN documentation

pub fn has_own_property(&self, property: &JsValue) -> bool[src]

The hasOwnProperty() method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

MDN documentation

pub fn is_prototype_of(&self, value: &JsValue) -> bool[src]

The isPrototypeOf() method checks if an object exists in another object's prototype chain.

MDN documentation

pub fn property_is_enumerable(&self, property: &JsValue) -> bool[src]

The propertyIsEnumerable() method returns a Boolean indicating whether the specified property is enumerable.

MDN documentation

pub fn to_locale_string(&self) -> JsString[src]

The toLocaleString() method returns a string representing the object. This method is meant to be overridden by derived objects for locale-specific purposes.

MDN documentation

pub fn to_string(&self) -> JsString[src]

The toString() method returns a string representing the object.

MDN documentation

pub fn value_of(&self) -> Object[src]

The valueOf() method returns the primitive value of the specified object.
