Current behavior

Component throws a TypeError: e.toFixed is not a function when min/max input is bound to string and value is populated with min/max value through spinner buttons.

Expected behavior

Cast to number or validate min/max inputs.

Indeed, the component doesn't parse the input explicitly as it expects to receive Number value:

https://www.telerik.com/kendo-angular-ui-develop/components/inputs/api/NumericTextBoxComponent/#toc-min
The required type is number.

Unfortunately, the min="2" property definition will set the min value to string value.

The workaround in this case is just to use the min Input property instead:

<kendo-numerictextbox [value]="value" [min]="2">
</kendo-numerictextbox>

Yes, it's easy in this simple example. But in my project I have 100+ kendo-numerictextbox component and some of them are bound to variables that came from API calls and it's hard to figure out which component's min/max is bound to string. So I hope you'll implement the explicit parse to Number 🙏
