JavaScript Modulus
JavaScript Modulus (%) Arithmetic Operator is used to find the remainder of division operation of two numbers, and return the result.
Modulus Operator Symbol
The symbol used for Modulus Operator is %
.
Syntax
The syntax to use Modulus Operator with operands is
operand1 % operand2
Examples
In the following example, we take two numeric values and find the remainder of their division operation using Modulus (%) Operator.
index.html
<!DOCTYPE html> <html lang="en"> <body> <pre id="output"></pre> <script> var a = 4; var b = 3; var result = a % b; document.getElementById('output').innerHTML += a + ' % ' + b + ' is ' + result; </script> </body> </html>
In the following example, we take two numeric values in exponential notation and find the remainder of their division using Modulus (%) Operator.
index.html
<!DOCTYPE html> <html lang="en"> <body> <pre id="output"></pre> <script> var a = 41e-2; var b = 121e-3; var result = a % b; document.getElementById('output').innerHTML += a + ' % ' + b + ' is ' + result; </script> </body> </html>
