This document describes the basic behaviour of an operator.

result = expression1 AndAlso expression2 result = expression1 OrElse expression2 ParameterDetailsresultRequired. Any Boolean expression. The result is the Boolean result of comparison of the two expressions.expression1Required. Any Boolean expression.expression2Required. Any Boolean express...

Linq queries are written using the Standard Query Operators (which are a set of extension methods that operates mainly on objects of type IEnumerable<T> and IQueryable<T>) or using Query Expressions (which at compile time, are converted to Standard Query Operator method calls). Query ...

Bit shift operations are not portable across all processor architectures, different processors can have different bit-widths. In other words, if you wrote int a = ~0; int b = a << 1; This value would be different on a 64 bit machine vs. on a 32 bit machine, or from an x86 based processo...

In most cases, the spread operator *. is identical to calling .collect { it.________ }. def animals = ['cat', 'dog', 'fish'] assert animals*.length() == animals.collect { it.length() } But if the subject is null, they behave a differently: def animals = null assert animals*.length() == null...

Operators are used to assign or compare values. They consist of a single symbol or keyword and are usually sandwiched between a left and a right value. For example: right = left. Operators are intrinsic to the language (such as =), and not functions such as those provided by System.Math.

Operators are methods Most operators are actually just methods, so x + y is calling the + method of x with argument y, which would be written x.+(y). If you write a method of your own having semantic meaning of a given operator, you can implement your variant in the class. As a silly example:...

Operators are listed top to bottom, in descending precedence. Operators with the same number have equal precedence and the same associativity. :: The postfix operators: [] () T(...) . -> ++ -- dynamic_cast static_cast reinterpret_cast const_cast typeid The unary prefix operators: ++ -- * ...

The Elvis operator evaluates based on Groovy-Truth of the condition-part.

Nearly all operators in R are really functions. For example, + is a function defined as function (e1, e2) .Primitive("+") where e1 is the left-hand side of the operator and e2 is the right-hand side of the operator. This means it is possible to accomplish rather counterintuitive effect...

Python operators have a set order of precedence, which determines what operators are evaluated first in a potentially ambiguous expression. For instance, in the expression 3 * 2 + 7, first 3 is multiplied by 2, and then the result is added to 7, yielding 13. The expression is not evaluated the other...
