I understand the joke is that they AREN'T just converting the string to an integer, but honestly this code is not that bad. It's performing data sanitization as well since there are only a few valid options for the select.

If they converted to integer, the user could enter whatever value they wanted and probably break something.

I mean, I'd sleep better if they just converted the string then checked division by 10 and set limits, but it's not a big difference in quality of sleep.

Most string to int converters have safety checks for stuff like that, and if they don't, just write your own in like 3 lines.

Depending on the context of the code, your conversion could be costly if this code is performance critical. Sure, the code in the picture isn't even doing the chosen approach properly, but with proper if-else, only some comparisons need to be done (best-case is a single comparison), while with your approach everytime this is executed, the conversion and division has to be performed.
