In JavaScript, we use comparison operators to compare two values and find the resulting boolean value (true or false). For example, // less than operator console.log(4 < 5); // Output: true Run Code In the above example, we used the < operator to find the boolean value for the cond...
In ordinary arithmetic, these logical operators have the value either TRUE (1) or FALSE (0), as shown above. Objects To create new variables, you will need to use the assignment operator ( <- ): 复制 > # Creating a new variable 'article' that has the value of 2 > article <- 2...
fn = new Formula(fn, null, LogicOperator.Not); }returnfn; } } 所述_parent变量用于构建公式树。您可以使用Closed属性测试树的分支是否关闭。这个属性在根分支中的值可以用来测试整个tableaux是否是关闭(状态)。 要测试分支是否包含公式,有两种方法:包含和否定。要决定一个分支是否关闭,必须检查是否存在一个公式...
