pre-decrement) the operator decreases the variable var1 by 1 but returns the value after decrementing. post-decrement) the operator decreases the variable var1 by 1 but returns the value before decrementing. The decrement operator is used as follows: Var newText5 = document.createTextNode("After pre-increment value of var1 = "+var1+" and X = "+X) //creates text along with ouput to be displayedĭ(newParagraph5) Var newParagraph5 = document.createElement("p")

The increment operator is used as follows: Var newText1 = document.createTextNode("var3 % var4 = "+ newvar1) ĭ(newParagraph1)

Var newParagraph1 = document.createElement("p") Var newText = document.createTextNode("var1 % var2 = "+ newvar) Var newParagraph = document.createElement("p") JavaScript modules operator (%) example with DOM The result will have the same sign as var1. The modulo function is the integer remainder of dividing var1 by That is, var1 modulo var2, in the above statement, where var1 and var2 are The modulus operator returns the first operand modulo the second operand, Hence, the modulo operator in javascript is just the remainder operator which will give negative output if the input is negative.In addition to four standard arithmetic operators (+, -, *, /), JavaScript provides the following arithmetic operators. Whereas both will work out their own ways in case the integers are negative. In this can both the operators will work the same. Hence, we conclude that the modulo operator in javascript will only work on the positive integers.

Modulo operator binds an arbitrary integer into a given range.In case the dividend and divisor are not positive integers, modulo will give the different output from the remainder operator.If both the dividend and divisor are positive integers, modulo will give the output as the reminder operator in the arithmetic operations.The output of this javascript program will be: 2 Difference between modulo operator and remainder operator: The output will be the dividend only if the user divided divisor input by an infinite number,ĭocument.getElementById("test").innerHTML = c.If the dividend is zero, the output will also be 0.When the user tries to divide infinity by infinity, the result will be NOT a NUMBER.If the dividend input is 0, the output will be NOT a NUMBER.There are some key features about modulo operator that user should be aware of: In case the inputs are string values, they are first converted into integer values. Where a is the dividend and b is the divisor.
