Type the program's output
number = 9
print('{:b}, {:d}, {:.2f}'.format(number, number, number))
Answer (1)
The program converts the integer 9 into binary, decimal, and floating-point representations and outputs them in a specific format.
Converts 9 to binary: 1001.
Keeps 9 as decimal: 9.
Converts 9 to floating-point with two decimal places: 9.00.
Combines the representations: 1001, 9, 9.00.
1001 , 9 , 9.00
Explanation
Understanding the Program We are given a Python program that assigns the integer value 9 to the variable number . The program then uses the format() method to output the value of number in three different formats: binary, decimal, and floating-point with two decimal places.
Binary Conversion First, we need to convert the integer 9 to its binary representation. The binary representation of 9 is 1001.
Decimal Representation Next, we keep the integer 9 as its decimal representation, which is simply 9.
Floating-Point Conversion Then, we convert the integer 9 to a floating-point number with two decimal places. This is 9.00.
Combining Representations Finally, we combine the three representations into a single string, separated by commas and spaces, as specified in the format string. The resulting string is '1001, 9, 9.00'.
Final Answer Therefore, the output of the program is: 1001, 9, 9.00
Examples
Understanding different number systems like binary, decimal, and floating-point is crucial in computer science. For instance, when working with low-level programming or data storage, it's essential to know how numbers are represented in binary. Decimal representation is what we use in everyday calculations, and floating-point representation is used for storing real numbers with fractional parts in computers. This problem demonstrates how a single number can be represented in multiple ways, each serving different purposes in computing.
