In the above program, parseFloat() is used to convert numeric string to number. If the string is a floating number, parseFloat() converts the string into floating point number.

The numbers are compared with one another using greater than or equal to >= operator. And the if...else if...else statement is used to check the condition.

Here, logical AND && is also used to check two conditions.

You can also use the JavaScript built-in Math.max() function to find the largest among the numbers.

Example2: Using Math.max()

Output

Enter first number: 5
Enter second number: 5.5
Enter third number: 5.6
The largest number is 5.6

Math.max() returns the largest number among the provided numbers.

You can use Math.min() function to find the smallest among the numbers.
