- What does lt; gt; (angle brackets) mean in MS-SQL Server?
30 <> operator means not equal to in MS SQL It compares two expressions (a comparison operator) When you compare nonnull expressions, the result is TRUE if the left operand is not equal to the right operand; otherwise, the result is FALSE If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL) See here : Not Equal To
- c - What does tilde (~) operator do? - Stack Overflow
The ~ 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 For example: 10101000 11101001 Original (Binary for -22,295 in 16-bit two's complement) 01010111 00010110 ~Original (Binary for
- What does the `%` (percent) operator mean? - Stack Overflow
1 That is the modulo operator, which finds the remainder of division of one number by another So in this case a will be the remainder of b divided by c
- What are bitwise shift (bit-shift) operators and how do they work?
The Operators >> is the arithmetic (or signed) right shift operator >>> is the logical (or unsigned) right shift operator << is the left shift operator, and meets the needs of both logical and arithmetic shifts All of these operators can be applied to integer values (int, long, possibly short and byte or char)
- Is there a difference between == and is? - Stack Overflow
The is operator compares the identity of two objects The == operator compares the values of two objects An object's identity never changes once it has been created; you may think of it as the object's address in memory You can control comparison behaviour of object values by defining a __cmp__ method or a rich comparison method like __eq__
- Is there a not equal operator in Python? - Stack Overflow
32 There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1 This will always return True and "1" == 1 will always return False, since the types differ Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different
- 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)
