## What actual underlying values are represented by true and false?

In computer science, the Boolean data type is a data type that has one of two possible values (usually denoted true and false) which is intended to represent the two truth values of logic and Boolean algebra..

## Is 0 True or false?

Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true. To make life easier, C Programmers typically define the terms “true” and “false” to have values 1 and 0 respectively.

## Is 0 true or false in Excel?

This means that TRUE is equal to a value of 1 while FALSE is 0. We can use this fact to make calculations in formulas.

## Does null evaluate to false PHP?

NULL essentially means a variable has no value assigned to it; false is a valid Boolean value, 0 is a valid integer value, and PHP has some fairly ugly conversions between 0 , “0” , “” , and false . Null is nothing, False is a bit, and 0 is (probably) 32 bits.

## What does == mean in Java?

equality operator”==” or equality operator in Java is a binary operator provided by Java programming language and used to compare primitives and objects. … so “==” operator will return true only if two object reference it is comparing represent exactly same object otherwise “==” will return false.

## Is a Boolean 1 bit?

A boolean is a true-or-false quantity, but a bit is actually an integer, just like char or int, but only one bit wide. When converting to these types, you can get different results. In the boolean world, 0 is false and anything else is true.

## Which of the following type of variables are special type that only has one value NULL?

A – NULL is a special type that only has one value: NULL. B – The special constant NULL is capitalized by convention, but actually it is case insensitive.

## Is true or == true Python?

The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True , while the expression 0 == 1 is False . Understanding how Python Boolean values behave is important to programming well in Python.

## Is 0 true or false in Java?

A 0 (zero) is treated as false. Where as in JAVA there is a separate data type boolean for true and false. In c and C++ there is no data type called BOOLEAN Thats why it uses 1 and 0 as true false value. and in JAVA 1 and 0 are count as an INTEGER type so it produces error in java.

## Is 1 True or false Matlab?

The logical data type represents true or false states using the numbers 1 and 0 , respectively. Certain MATLAB® functions and operators return logical values to indicate fulfillment of a condition. You can use those logical values to index into an array or execute conditional code.

## Is 0 True or false C++?

Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true. C++ is backwards compatible, so the C-style logic still works in C++. ( “true” is stored as 1, “false” as 0. )

## Can a value be both true and false Javascript?

The result is false if the argument is +0, −0, or NaN; otherwise the result is true. The result is false if the argument is the empty String (its length is zero);…Truth, Equality and JavaScript.Type(x)ValuesResultBooleanx and y are both true or both falsetrueObjectx and y reference same objecttrueotherwise…false4 more rows•Feb 7, 2011

## Does 1 represent true or false?

The number 0 is considered to be false and all other numbers are considered to be true…. … 1 is considered to be true because it is non-zero. The fourth expression assigns a value of 0 to i. 0 is considered to be false.

## What is Boolean example?

A Boolean variable has only two possible values: true or false. … In this example, when the boolean value “x” is true, vertical black lines are drawn and when the boolean value “x” is false, horizontal gray lines are drawn.
