# typecheck-number - use `angular.isNumber` instead of `typeof` comparisons

You should use the angular.isNumber method instead of the default JavaScript implementation (typeof 3 === "[object Number]").

## Examples

The following patterns are considered problems;

    /*eslint angular/typecheck-number: 2*/

    // invalid
    typeof someNumber === 'number' // error: You should use the angular.isNumber method

The following patterns are **not** considered problems;

    /*eslint angular/typecheck-number: 2*/

    // valid
    angular.isNumber(someNumber);

## Version

This rule was introduced in eslint-plugin-angular 0.1.0
