Parameters
| Parameter | Type | Description |
|---|---|---|
| value | string | number | typeof Field.SKIP_SETUP | (Optional) The initial value of the field. Should cast to a number. Defaults to 0. Also accepts Field.SKIP_SETUP if you wish to skip setup (only used by subclasses that want to handle configuration and setting the field value after their own constructors have run). |
| min | string | number | null | (Optional) Minimum value. Will only be used if config is not provided. |
| max | string | number | null | (Optional) Maximum value. Will only be used if config is not provided. |
| precision | string | number | null | (Optional) Precision for value. Will only be used if config is not provided. |
| validator | FieldNumberValidator | null | (Optional) A function that is called to validate changes to the field's value. Takes in a number & returns a validated number, or null to abort the change. |
| config | FieldNumberConfig | (Optional) A map of options used to configure the field. See the [field creation documentation]https://developers.google.com/blockly/guides/create-custom-blocks/fields/built-in-fields/number#creation for a list of properties this parameter supports. |
