How does modulo operator work for negative numbers?

How does modulo operator work for negative numbers?

The modulus of a negative number is found by ignoring the minus sign. The modulus of a number is denoted by writing vertical lines around the number. Note also that the modulus of a negative number can be found by multiplying it by −1 since, for example, −(−8) = 8.

How does modulo work with negative numbers in Python?

5. Modulo with Negative Numbers. Python modulo operator always return the remainder having the same sign as the divisor. This can lead to some confusion with the output.

How does the modulo operation work?

The modulo operation (abbreviated “mod”, or “\%” in many programming languages) is the remainder when dividing. For example, “5 mod 3 = 2” which means 2 is the remainder when you divide 5 by 3. An odd number is “1 mod 2” (has remainder 1).

What does the Java modulo operator return when given a negative number?

The sign of the first operand decides the sign of the result. x \% y always equals x \% -y . You can think of the sign of the second operand as being ignored.

How do you do modulo operations in Python?

The Python modulo operator calculates the remainder of dividing two values. This operator is represented by the percentage sign (\%). The syntax for the modulo operator is: number1 \% number2. The first number is divided by the second then the remainder is returned.

What does Modulo do in Python?

Basically, Python modulo operation is used to get the remainder of a division. The modulo operator(\%) is considered an arithmetic operation, along with +, –, /, *, **, //. In most languages, both operands of this modulo operator have to be an integer.

How does modulo work in Python?

Does modulo return negative?

These functions give the same values for positive arguments, but the modulus always returns positive results for negative input, whereas the remainder may give negative results.

How do you do negative modulo in Java?

Is modulo a math operator?

The modulo operator, denoted by \%, is an arithmetic operator. The modulo division operator produces the remainder of an integer division. Syntax: If x and y are integers, then the expression: produces the remainder when x is divided by y.

How do modulo operations work?

Modulo operations essentially work on number “classes” instead of on numbers. A number class is a group of numbers, such that (1) every number falls in exactly one class, and (2) there are only a finite number of classes. Every class can be represented by any element of the class, at choice.

What is the modulo of a negative number?

But things get a little more tricky when you throw negative numbers into the mix. The modulo or often referred to as “mod” represents the remainder of a division. In 1801 Gauss published a book covering modular arithmetics.

Is there a modulo operator in Python for negative numbers?

As pointed out, Python modulo makes a well-reasoned exception to the conventions of other languages. This gives negative numbers a seamless behavior, especially when used in combination with the // integer-divide operator, as \% modulo often is (as in math. divmod ):

What is the difference between modulo and remainder operators in C?

Modulo and remainder operators differ with respect to negative values. With a remainder operator, the sign of the result is the same as the sign of the dividend (numerator) while with a modulo operator the sign of the result is the same as the divisor (denominator). C defines the \% operation for a \% b as:
