Nettet5. aug. 2010 · >> and << are the Right-Shift and Left-Shift bit-operators, i.e., they alter the binary representation of the number (it can be used on other data structures as well, but Python doesn't implement that). They are defined for a class by __rshift__ (self, shift) and __lshift__ (self, shift). Example: NettetWhen shifting right with an arithmetic right shift, the least-significant bit is lost and the most-significant bit is copied. Languages handle arithmetic and logical right shifting in different ways. Java provides two right shift operators: >> does an arithmetic right shift and >>> does a logical right shift. Nettet29. sep. 2024 · The bitwise left shift operator in Python shifts the bits of the binary representation of the input number to the left side by a specified number of places.

"Nettet5. sep. 2024 · It works in C (for specific values of N, depending on the type used, typically something like 8 or 32), because the bits that are shifted out to the left are automatically truncated. You need to do this explicitly in Python to get the same behaviour. " - Left bit shift python

NettetIn Python, they are Bitwise Operators known as Bitwise left shift (<<) and Bitwise right shift (>>). What are Operators? Operators are the special symbols used to do arithmetic and logical computations. Operators are used to alter values and variables. The value on which the operator operates is referred to as the Operand. Python Shift Operators NettetI'm working with 64 bit unsigned integers and after bit shifting comparing the value before decoding the rest of the bit values.

NettetIn the bit shift version the key instruction is shll $2, %eax which is a shift left logical - there's the divide, and everything else is just moving values around. In the divide version, you can see the idivl %r8d - but just above that is a cltd (convert long to double) and some additional logic around the spill and reload.
