What's the reason high-level languages like C#/Java mask the bit shift count operand?

This is more of a language design rather than a programming question. The following is an excerpt from JLS 15.19 Shift Operators: > If the promoted type of the left-hand operand is `int`, only the five lowest-order bits of the right-hand operand are used as the shift distance. > If the promoted type of the left-hand operand is `long`, then only the six lowest-order bits of the right-hand operand are used as the shift distance. This behavior is also specified in C#, and while I'm not sure if it's in the official spec for Javascript (if there's one), it's also true based on my own test at least. The consequence is that the following is true: (1
