The not operator enables you to reverse the meaning or logic of a given condition or object. In programming, this kind of feature is known as negative logic or negation. Using negative logic correctly can be tricky because this logic is difficult to think about and understand, not to mention...
It shows that in such Boolean structure, deductions comprise physico-chemical meaning. In particular, codons with adenine as a second base coding to hydrophilic amino acids are not deductible from codons with uracil in the same position, which code to hydrophobic amino acids. Boolean deductions ...
We turn to explain the meaning of (3) being small by discussing these random walks.Footnote 3 The operators U and D induce random walks on the jth level X(j) of the simplicial complex. Recall that our simplicial complexes come with distributions \Pi _{j} on the j-faces.Definition 4.1(...
Enums are much more readable (in books, documentation, code reviews, etc). Consider a method call that looks such as: FileStream f = File.Open (“foo.txt”, true, false); This call gives you no context whatsoever to understand the meaning behind true and false. Now consider if the cal...
Regarding the example - I create a FB for the control word encoding (or anywhere I have to encode/decode bits). Only in this FB, will "evil" bit coding occur... The "traditional" solution would use VAR_INPUTS and VAR_OUTPUTS and the FB would have to be called to calculate the CW...

Martin's series on an interstellar spacecraft where programmers hone their coding skills. In this twelfth tip in the series, the crew learns that Boolean arguments loudly declare that the function does more than one thing. They are confusing and should be eliminated. Like this article? We ...
To reiterate, this is a very bad way to write code. If I saw this in PR review, I would suggest adding parentheses to make the meaning obvious. In "legacy" code, this pattern amounts to a puzzle, and solving the puzzle requires understanding implicit precedence rules in detail....
cannot be deleted or altered. A variable declaration has its meaning at the time of compilation only, compiler needs actual variable definition at the time of linking of the program. Though you can declare a variable multiple times in your program, but it can be defined only once in a file...
Other Boolean operators and their meaning is as mentioned in the above snapshot.Using Boolean Operators AND −If {CUSTOMER.CUSTOMER_NAME} [1 to 2] = "AN" and ToText({CUSTOMER.CUSTOMER ID}) [2] = "4" then "TRUE" Else "FALSE" Using Boolean Operators AND and OR −...
