Check if input is integer in 05AB1E

Question

I want to check if the input is a positive integer in the language 05AB1E. This should output something that acts as a boolean. For example,

• "oof" ==> false
• 7.5 ==> false
• 19 ==> true

...

Is there a way to do this? Numeric strings can output true or false. It depends on the nature of the input.
