If you need a simple introduction to the hardware side of logic thenBebop to the Boolean Boogie: An Unconventional Guide to ElectronicsbyClive Maxfield is an easy read. If you like "For Dummies" thenLogic For Dummiesby Mark Zegarelli is worth a look but notice that it goes well beyond the...
JS_Boolean Logic Comparisons > < >= <= == != === !== == double equals check for equality of value, but not equality of type it coerces both values to the same type and then compares them this can lead to some unexpected results. 0 == ' '; //true 0 == false; //true null...
In spreadsheet applications, Boolean logic is used extensively within conditional formulas to make decisions based on specific criteria. For example, using the IF function, a user can create a formula that checks whether a condition is true or false and then performs different actions based on the...

At the heart ofaBoolean Logicexpressionis the idea that all values are either true or false.In other words, Boolean means using operators to compare variables against the criteria you define to determine if the variables meet them. A Boolean operation, then, is the construction of a logical ...

T or B mean not N(F), then N(F) means that not T and not B.’ The sentence is of the form ‘If …, then …’, which is expressed by writing an arrow from the condition to the consequent, which are bracketed, to give ‘(T or B ...

A search for data that meets several criteria by using the Boolean operators AND, OR and NOT (seeBoolean logic). For example, the request: "Search for all Spanish and French speaking employees who have MBAs" would be written as follows if the query were expressed on a command line. Spanis...
is clear. This is called "short circuiting". The && short circuits at the first false -- then the whole expression must be false. The || short circuits at the first true -- then the whole expression must be true. Suppose we have an int i, and we want to check if i is 2 or ...
