Explain how you add fixed-width digits in a decimal number system. How do you do this in binary? How do you do this in hexadecimal? Explain how you subtract numbers in digits in a decimal number system. How do you do this in binary? How do you do this in hexadecimal

In this question, you are provided with a decimal floating-point number. You are asked to encode this value into its IEEE-754 floating-point representation in the form of 8 hexadecimal digits. If rounding is needed, use rounding to the nearest floating-point number. Do NOT add any spaces or commas to your answer. Represent, i.e., encode, 262148.140625 into a 32-bit single-precision IEEE-754 FP value. If rounding is needed, use rounding to the nearest FP number. Your answer MUST BE JUST 8 hexadecimal digits. Write each hexadecimal digit in a field by itself. B } Ox D R D = = }
