Example 2: Add Two Numbers Entered by the User const num1 = parseInt(prompt(‘Enter the first number ‘)); const num2 = parseInt(prompt(‘Enter the second number ‘)); Then, the sum of the numbers is computed. const sum = num1 + num2; Finally, the sum is displayed.
Example 1: Sum of Natural Numbers Using for Loop The parseInt() converts the numeric string value to an integer value. The for loop is used to find the sum of natural numbers up to the number provided by the user. The value of sum is 0 initially. Then, a for loop is used to iterate from i = 1 to 100 .
sum() function in D3. js is used to return the sum of the given array’s elements. If the array is empty then it returns 0. Parameters: This function accepts a parameters Array which is an array of elements whose sum are to be calculated.
- function multiplyBy()
- num1 = document. getElementById(“firstNumber”). value;
- num2 = document. getElementById(“secondNumber”). value;
- document. getElementById(“result”). innerHTML = num1 * num2;
- function divideBy()
Dividing. The division operator ( / ) divides numbers.
