逻辑布尔运算符使用bool操作数执行逻辑运算。 运算符包括一元逻辑非 (!)、二元逻辑 AND (&)、OR (|) 以及异或 (^),二元条件逻辑 AND (&&) 和 OR (||)。 一元!(逻辑非)运算符。 二元&(逻辑与)、|(逻辑或)和^(逻辑异或)运算符。 这些运算符始终计算两个操作数。
Nullable Boolean logical operatorsFor bool? operands, the & (logical AND) and | (logical OR) operators support the three-valued logic as follows:The & operator produces true only if both its operands evaluate to true. If either x or y evaluates to false, x & y produce...

KQL operators for complex queries KQL syntax includes several operators that you can use to construct complex queries. Boolean operators You use Boolean operators to broaden or narrow your search. You can use Boolean operators with free text expressions and property restrictions in KQL queries. Table...
For operator precedence, seeSection 14.4.1, “Operator Precedence”. The precedence and meaning of some operators depends on the SQL mode: Expression Term Notes For literal value syntax, seeSection 11.1, “Literal Values”. For identifier syntax, seeSection 11.2, “Schema Object Names”. ...
You can also supply a lambda expression when the argument type is anExpression<TDelegate>, for example in the standard query operators that are defined in theQueryabletype. When you specify anExpression<TDelegate>argument, the lambda is compiled to an expression tree. ...
The most common use of bitwise operators is for representing flag bits (Boolean values packed into 1 bit each). A floating-point number is converted to an integer by discarding any digits after the decimal point. A positive integer is converted to an unsigned hexadecimal value with a maximum...
The order of the query terms is not important for the matching, only the distance. Any number of terms can be combined with theNEARoperators. NEARoperands may be single terms, phrases, or BooleanORorANYoperator expressions. Wildcards are accepted. ...
BooleanExample.as The following example toggles and displays each corresponding value for the Boolean object: Copy package { import flash.display.Sprite; public class BooleanExample extends Sprite { private var flag:Boolean; public function BooleanExample() { trace(flag); // false toggle(); trace...
JavaScript booleans can have one of two values:trueorfalse. The Boolean() Function You can use theBoolean()function to find out if an expression is true: Example Boolean(10>9) Try it Yourself » Or even easier: (10>9) Try it Yourself » ...
