These operators cause the bits in the left operand to be shifted left or right by the number of positions specified by the right operand.\ More on bitwise math may be found here. text/html 2024-02-16T01:04:15+02:00 https://code-reference.com/arduino/bitwise_operators/bitwiseand?rev=1708041855&do=diff Bitwise AND (&) The bitwise operators perform their calculations at the bit level of variables. They help solve a wide range of common programming problems. Much of the material below is from an excellent tutorial on bitwise math wihch may be found here. text/html 2024-02-16T01:04:15+02:00 https://code-reference.com/arduino/bitwise_operators/bitwisecompoundand?rev=1708041855&do=diff Description The compound bitwise AND operator (&=) is often used with a variable and a constant to force particular bits in a variable to the LOW state (to 0). This is often referred to in programming guides as “clearing” or “resetting” bits. text/html 2024-02-16T01:04:16+02:00 https://code-reference.com/arduino/bitwise_operators/bitwisecompoundor?rev=1708041856&do=diff Description The compound bitwise OR operator (|=) is often used with a variable and a constant to “set” (set to 1) particular bits in a variable. Syntax: x |= y; // equivalent to x = x | y; Parameters x: a char, int or long variable y: an integer constant or char, int, or long text/html 2024-02-16T01:04:15+02:00 https://code-reference.com/arduino/bitwise_operators/bitwisexornot?rev=1708041855&do=diff The bitwise NOT operator in C++ is the tilde character ~. Unlike & and |, the bitwise NOT operator is applied to a single operand to its right. Bitwise NOT changes each bit to its opposite: 0 becomes 1, and 1 becomes 0. For example: 0 1 operand1 ---------- 1 0 ~ operand1 int a = 103; // binary: 0000000001100111 int b = ~a; // binary: 1111111110011000 = -104 You might be surprised to see a negative number like -104 as the result of this operation. This is because the hi…
