logical operators in if statementMATLAB Online で開く@Kenneth Lamury: what you proposed does not make any difference, because theoperator precedence rulesclearly state that > and < have a higher precedence than&&. So adding brackets around the two equivalence operations makes no difference whatsoever...
Value_if_false(optional argument) – The value that will be returned if the logical_test evaluates to FALSE. When using the IF function to construct a test, we can use the following logical operators: = (equal to) > (greater than) >= (greater than or equal to) < (less than) <= (...
logical operators such as OR, AND, and NOT return the Boolean value “True or False”. These operators help us to combine multiple decisions-driven statements. Logical operators are used along with conditions like “if”, “if-else”, and “elif” to reduce multiple lines...

When there are multiple dependent conditions, users can use logical operators such as AND and OR inside a single IF statement. The syntax of using AND/OR conditions with the IF statement is as follows: If condition_1and condition_2 Then ...

• Programmers use logical operators to write compound conditionals. • The NOT operator (negation operator) is coded using the exclamation point, !. • The ! can be used to flip-flop a boolean. • De Morgan’s Law states: !(A && B) = !A || !B and also !(A || B) = ...
Logical operators are used to invert or combine other expressions. -not The -not operator flips an expression from $false to $true or from $true to $false. Here is an example where we want to perform an action when Test-Path is $false. PowerShell Copy if ( -not ( Test-Path -Path...
The three primary logical operators are:Operator Meaning AND In order for the entire conditional expression to be true, the comparisons on the left and right side of the AND must both be true. If either of them is false, then the entire statement is false. OR For the entire conditional ...
