In many engineering applications your sensor value or control command will need to be restricted between two values. In this case, make sure that an integer value passed to your method doesn't go above $99$ or below $-100.$

Keeping a sensor or control value bounded like this is sometimes $($often$?)$ referred to as "thresholding" or "saturating" or "limiting".

Regardless of what you call it$,$ it's a super common thing to do$.$
