Settings

Set these settings on a NumberFormatter object using its set() and setAll() methods. Read about settings concept.

#bigNumberPrefixes

Type INumberSuffix[]

Suffixes for big numbers and the values they stand for, such as "M" for a million. Used by the a modifier of the number format.

#bytePrefixes

Type INumberSuffix[]

Suffixes for data sizes and the byte counts they stand for, such as "KB" for 1024. Used by the b modifier of the number format.

#forceLTR

Type undefined | false | trueDefault falseSince 5.3.13

Forces formatted numbers to read left to right, even in a right-to-left layout.

#intlLocales

Type undefined | string

Locale for formats given as Intl.NumberFormat options, such as "de-DE". The browser's locale if not set.

#negativeBase

Type undefined | numberDefault 0

Values below this use the negative part of the format (after the first |), and a value equal to it the zero part (after the second |). The minus sign still shows only for values below 0.

#numberFormat

Type string | NumberFormatOptionsDefault "#,###.#####"

Format used when no other format is given: a format string, or options for Intl.NumberFormat.

#numericFields

Type string[]

Data fields that hold numbers. Text placeholders with these fields are formatted as numbers even without formatNumber().

#smallNumberPrefixes

Type INumberSuffix[]

Suffixes for small numbers and the values they stand for, such as "m" for a thousandth. Used by the a modifier of the number format.

#smallNumberThreshold

Type undefined | numberDefault 1

Numbers below this use smallNumberPrefixes with the a modifier;

#animations

Type ArrayInherited from IEntitySettingsSince 5.20.8

Animations the element plays on its own, described as data - so they can be set from a JSON config and saved with it.

Each one animates a setting of the element (or, with target: "dataItem", a value of its data item - a map point's positionOnLine, say). They start when the setting is applied, restart when it changes, and stop when the element is disposed. A saved config keeps what was configured, never a value caught half way through an animation.

sprite.set("animations", [
  { key: "rotation", to: 360, duration: 4000, loops: 0 },
  { key: "scale", from: 1, to: 1.3, duration: 800, loops: 0, yoyo: true, easing: "sine" }
]);

#id

Type undefined | stringInherited from IEntitySettings

A unique ID for looking the element up in root.entitiesById. Setting an ID that another element already has throws an error.

#ignoreThemes

Type undefined | false | trueDefault falseInherited from IEntitySettingsSince 5.15.6

Ignores themes: no theme rule applies to the element, not even one of the default theme.

#stateAnimationDuration

Type undefined | numberDefault 0Inherited from IEntitySettings

How long, in milliseconds, a switch from one state to another animates.

0 switches at once.

#stateAnimationEasing

Type $ease.EasingDefault out(cubic)Inherited from IEntitySettings

Easing of the animated switch from one state to another.

#themes

Type ArrayInherited from IEntitySettings

Themes applied to the element and everything inside it.

#themeTags

Type ArrayInherited from IEntitySettings

Tags that theme rules can target. They also count for the element's children, so a rule can match a child by a tag of its parent.

More info: Themes

#themeTagsSelf

Type ArrayInherited from IEntitySettings

Tags that theme rules can target, like themeTags, but only for this element, not its children.

More info: Themes

#userData

Type anyInherited from IEntitySettings

Any data of your own to keep with the element.

Private settings

These are read-only settings accessible from a NumberFormatter object using its getPrivate() method. Read about private settings.

NumberFormatter does not have any private settings.

#animate(options: AnimationOptions)

Returns AnimationInherited from Settings

Animates a setting from its current value (or from) to to. The setting jumps to from at once. With duration 0, or no value to start from, it is set to to at once and the returned animation is already stopped.

callback?: undefined | (value: [""], target: this, key: Key) => void)

Returns voidInherited from Settings

More info: Events: settings value change

#on(key: Key,
callback: (value: [""], target: this, key: Key) => void)

Returns IDisposerInherited from Settings

Calls callback each time the value of setting key changes or is removed. Setting the same value again does not call it.

More info: Events: settings value change

#once(key: Key,
callback: (value: [""], target: this, key: Key) => void)

Returns IDisposerInherited from SettingsSince 5.20.4

Like on(), but the callback is removed after it is called once.

debounceDelay: number)

Returns IDisposerInherited from SettingsSince 5.20.4

More info: Events: settings value change

#onDebounced(key: Key,
callback: (value: [""], target: this, key: Key) => void,
debounceDelay: number)

Returns IDisposerInherited from Settings

Like on(), but waits until setting key has not changed for debounceDelay milliseconds, then calls callback once with the latest value.

More info: Events: settings value change

#onPrivate(key: Key,
callback: (value: [""], target: this, key: Key) => void)

Returns IDisposerInherited from Settings

Calls callback each time the value of private setting key changes.

More info: Events: settings value change

#onPrivateDebounced(key: Key,
callback: (value: [""], target: this, key: Key) => void,
debounceDelay: number)

Returns IDisposerInherited from Settings

Like onPrivate(), but waits until private setting key has not changed for debounceDelay milliseconds, then calls callback once with the latest value.

More info: Events: settings value change

#remove(key: Key)

Returns voidInherited from Entity

Removes the value set for setting key. The setting goes back to the value from a theme or template, if one has it.

More info: Settings

#removeAll()

Returns voidInherited from Settings

Removes all settings, as remove() does for each one.

More info: Settings

#set(key: Key,
value: Value)

Returns ValueInherited from Entity

Sets setting key to value and returns value. A value set this way overrides themes and templates, and stops any animation of the setting.

More info: Settings

#setAll(settings: Partial)

Returns voidInherited from Settings

Sets several settings at once, from an object of key-value pairs.

More info: Settings

#setTimeout(fn: () => void,
delay: number)

Returns IDisposerInherited from Entity

Calls fn after delay milliseconds, unless the object is disposed first. Disposing the returned disposer cancels it.

Events

NumberFormatter does not have any events.
