WebBitwise Operators in Scala Coming to Bitwise Scala operator, we have seven in Scala. But first, let’s see the truth table for these: Let’s take two values: scala> var a=60 //Its binary is 00111100 a: Int = 60 scala> var b=13 //Its binary is 00001101 b: … WebThe bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue. Both operands have the same precedence and are left-to-right associative. Operator. Usage.

WebScala - right shift operator The Bitwise right shift operator (>>) takes the two numbers and right shift the bits of first operand by number of place specified by second operand. For example: for right shifting the bits of x by y places, the expression ( x>>y) can be used. It is equivalent to dividing x by 2y. WebFeb 18, 2024 · Check whether the K-th bit is set or not Using Left Shift Operator: To solve the problem follow the below idea: Left shift given number 1 by k to create a number that has only set bit as k-th bit. temp = 1 << k If bitwise AND of n and temp is non-zero, then result is SET else result is NOT SET.
