The Remainder or Modulus Operator in Java

Java modulo operator

The order in which the operations are carried out is determined by the precedence of each operator in the expression. He loves Open source technologies and writing on JournalDev has become his passion. It's surprising because you don't normally think of real number division as producing remainders. Therefore taking an int % int returns another int. If we try to use the modulo operator with any other type of variable, we will get a compilation error.

Java modulo operator

It's a binary operator i. Going the other way from days, hours, minutes and seconds to milliseconds is easier. Hence, if + is applied on two numeric quantities it performs arithmetic addition, and if it is applied on two strings it concatenates them together. Since it return remainder value in division operation it is also known as remainder operator. LluisMartinez This is one of the most misquoted sayings in computing. It takes modulus using two operands and assign the result to left operand. For more complicated answers see.

Java also provides unary plus + and unary minus - to make a numeric value positive or negative. The next chapter will explain about loop control in Java programming. For floating-point calculations, however, division by zero simply yields an infinite result or NaN: Modulo Operator The modulo operator % returns the remainder when the first operand is divided by the second operand an integral number of times. The left operands value is moved right by the number of bits specified by the right operand. Here, operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom. The sign of the result follows the sign of the dividend. Our tutorials are regularly updated, error-free, and complete.

How Operators Work in Java

Java modulo operator

Be sure to use parentheses when you want to combine addition with concatenation. For example, in many cases like or , you can use modulus operator with 10 to get the last digit, for example, 101%10 will return 1 or 1234%10 will return 4, the last digit. In Java, the sign of the remainder follows the dividend, not the divisor as you would expect. Please enter an integer: 9 9 is odd. See if number is divisible evenly by 4, 3 and 2. BigInteger provides functions for both and the specifications for them explain the difference quite well.

Here are the utility methods to check if the integer is even or odd. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. It adds right operand to the left operand and assign the result to left operand. Arithmetic operators can be applied on any numeric type: byte, short, int, long, float, or double. In case of even number, number%2 will return 0 while if a number is odd then number%2 will return 1. Java has %, the remainder operator, but does not have a built-in modulus operator or function.

Java modulo operator

The goal of the operator is to decide, which value should be assigned to the variable. Java division is truncated division. The following Java program demonstrates the use of modulo operator. Table 1: Java arithmetic operators Operator Operation Associativity + Addition Also used for string concatenation. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. Whereas the x % n operator maps x to n in the range of -n,n. Here: We compute a hash code for a String based on its characters and length.

Modulo or Remainder Operator in Java

Java modulo operator

Java provides a rich set of operators to manipulate variables. It also illustrates the difference between floating-point division and integer division. It multiplies right operand with the left operand and assign the result to left operand. Table 1: Java arithmetic operators Operator Operation Associativity + Addition Also used for string concatenation. This kind of mod operator does not exist in C or C++ where the mod operator only works with int operands.

Based on operator precedence the modulus will be evaluated before the comparison. The Java Language Specification correctly refers to it as a remainder operator. If the least significant bit is 0 then the number is even. The chapter will describe various types of loops and how these loops can be used in Java program development and for what purposes they are being used. The evaluated result is a double value.

Mixed Base Calculations The modulus operator is useful in time calculation, e. Note the violation of the naming conventions. Often this subtle distinction doesn't matter. Numeric values are by default positive, if they are not led by any sign. The example code is available in the. Here, operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom.
