If x and y are non-integer values x % y is computed as x – n * y, where n is the largest possible integer that is less than or equal to x / y (more details in the C# 4.0 Specification in section 7.8.3 Remainder operator).
- What is the difference between & and && in Java?The bitwise AND " &" operator produces 1 if and only if both of the bits in its operands are 1. However, if both of the bits are 0 or both of the bits are different then this operator produces 0. To be more precise bitwise AND " &" operator returns 1 if both of the two bits is 1 and it returns 0 if any of the bits is 0. From the wiki page:
- When should I use ?? (nullish coalescing) vs || (logical OR)?The ?? operator was added to TypeScript 3.7 back in November 2019. And more recently, the ?? operator was included in ES2020, which is supported by Node 14 (released in April 2020). When the nullish coalescing operator ?? is supported, I typically use it instead of the OR operator || (unless there's a good reason not to).
- Pipe (|) operator in Java - Stack Overflow| is the "bitwise or" operator. in a|b, if nth bit of a and/or b is 1, the nth bit of the result will be 1. 3 is 11 in binary. 4 is 100 in binary. 0 1 1 or or or 1 0 0 = = = 1 1 1 And 111 happens to be the binary representation of 7.
- c - What does tilde (~) operator do? - Stack OverflowThe ~ operator in C++ (and other C-like languages like C and Java) performs a bitwise NOT operation - all the 1 bits in the operand are set to 0 and all the 0 bits in the operand are set to 1. In other words, it creates the complement of the original number.
