@fjarrett This is my favorite way of checking if the number is correct. It doesn't involve any type juggling like trimming zeros etc. It is `true` only if the value is correct number - the result is exactly the same like if we checked it against `^[1-9]\d*$` pattern, just nicer in my opinion. So:
`'01' is **false**
'1'  is **true**
1    is **true**
1.0  is **false**`
