JavaScript Math: Exercise-28 with Solution

Round Integer to Next Multiple of 5

Write a JavaScript function to round up an integer value to the next multiple of 5.

Test Data:
console.log(int_round5(32));
35
console.log(int_round5(137));
140

Sample Solution:

JavaScript Code:

// Define a function named int_round5 that rounds a number up to the nearest multiple of 5.
function int_round5(num)
{
    // Divide the number by 5, round the result up to the nearest integer, then multiply by 5.
    return Math.ceil(num/5)*5;
}

// Output the result of rounding 32 up to the nearest multiple of 5 to the console.
console.log(int_round5(32));
// Output the result of rounding 137 up to the nearest multiple of 5 to the console.
console.log(int_round5(137));
// Output the result of rounding 142 up to the nearest multiple of 5 to the console.
console.log(int_round5(142));

Output:

35
140
145
