What is logical operator example?
For example, a && b returns true when both a and b are true (i.e. non-zero). Logical OR operator: The ‘||’ operator returns true even if one (or both) of the conditions under consideration is satisfied. Otherwise it returns false. For example, a || b returns true if one of a or b or both are true (i.e. non-zero).
What are the main logical operators?
A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT .
Is == a logical operator?
Comparison operators — operators that compare values and return true or false . The operators include: > , < , >= , <= , === , and !== ... Logical operators — operators that combine multiple boolean expressions or values and provide a single boolean output. The operators include: && , || , and ! .
Which is not a logical operator?
The NOT logical operator reverses the true/false outcome of the expression that immediately follows. ... You can substitute ~ or ¬ for NOT as a logical operator. NOT can be used to check whether a numeric variable has the value 0, 1, or any other value. For example, all scratch variables are initialized to 0.

What are Boolean operators in GIS?
It forms a mathematical structure that is based only upon the values 1 (true) and 0 (false). In addition, Boolean algebra provides different links that can be “true” or “false” but never both. The Boolean operators that are used in GIS for linking two spatial selection criteria are AND, OR, XOR, and NOT .
