WebApr 1, 2024 · The bitwise NOT operator (~) is a unary operator, meaning it operates on a single operand. It inverts all the bits of its operand. For example, if the operand is 1010(in binary), the NOT operator will give 0101(in binary) as output. Let’s take an example to understand how the bitwise NOT operator works. WebApr 5, 2024 · You can use optional chaining when attempting to call a method which may not exist.

The unary prefix ! operator computes logical negation of its operand. That is, it produces true, if the operand evaluates to false, and false, if the operand evaluates to true: The unary postfix ! operator is the null-forgiving operator. See more The & operator computes the logical AND of its operands. The result of x & y is true if both x and y evaluate to true. Otherwise, the result is false. The & operator evaluates both … See more The operator computes the logical OR of its operands. The result of x y is true if either x or y evaluates to true. Otherwise, the result is false. … See more The ^ operator computes the logical exclusive OR, also known as the logical XOR, of its operands.

It helps if you look at it in binary. First of all, as you know, negative numbers are expressed as (highest possible unsigned number plus 1 minus value). So -1 in a 16-bit integer, which has the highest unsigned value of 65535, would be 65536-1=65535, i.e. 0xffff in hex, or 1111 1111 1111 1111 in binary. So: 1 in binary = 0000 0000 0000 0001. can hrothgar wear hats
