Program Explanation

Scanner class is a function available(predefined) in java library to get input from user via keyboard and stores the same in a variable.

Here it reads input number and stores it in a variable num.

Format Specifier "%.2f" reads output as 2 decimal point floating number.

(fractional number) System.out.println is a function available(pre defined) in java library which is used to print the specified content in Monitor.

Here it prints the value of the variable num.

Format Specifier "%.2f" prints value as Floating Point Number with 2digit Precision(.00).
