- Question 6 Full explain this questionarrow_forwardSuppose that we use the floating-point format with 12 decimal digits, SEEEMMMMMMMM, to rep- resent a real number, where S is the digit to represent the sign of the mantissa (use 0 for pos- itive and 5 for negative), EEE are the 3 digits to represent the exponent in excess-500 format, MMMMMMMM are the 8 digits to represent the magnitude of the mantissa, and the decimal point of the mantissa is right to the left of MMMMMMMM (i.e., SEEEMMMMMMMM representing the real number ±0.MMMMMMMM × 10EEE-500) What is the second largest positive number that can be represented in this for- mat? How much less is this number compared to the largest number? Can you represent a number located somewhere between the largest number and the second largest number?arrow_forwardHow is the number 2 represented in the floating point data type format?arrow_forward

What are the binary equivalents of the following hexadecimal numbers? 66CCFF; 3366FF; FFFFFF; 123456; ABCDEF;arrow_forwarde.Given the following contents of Fl, express the contents in both exponent and decimal form: i. 0263795 ii. 1757890 g. How would 374.577 be approximated in FL h. How would zero be represented in FL?arrow_forwardEnter the Single Precision Floating Point (SPEP) in hexadecimal for the decimal value -14.5.arrow_forward
- Why is normalized form often used to store floating-point numbers? What are the advantages of putting a bias in the exponent rather than a sign bit?arrow_forward1) Find the equivalent decimal value of the following floating-point representation using IEEE 754 standard single-precision (32-bit floating-point number with bias = 127) 1 0111 1111 1110 0000 0000 0000 0000 000 (The quiz is expecting a decimal numeric entry. It will automatically suppress leading and trailing zeros. It will display your answer with commas every third digit.) 2) Find an IEEE 754 floating-point representation of -74.2 decimal number. Enter 32 bits without a space. (The quiz is expecting a fill in the blank text string in the entry box and grades on an exact match with the expected result. The answer should be formatted as a 32-bit IEEE 745 binary number representation)arrow_forwardAssume we are using the simple model for floating-point representation discussed in the class (the representation uses a 14-bit format, 5 bits for the exponent with an Excess-M, a significand of 8 bits, and a single sign bit for the number): Convert 12.345 to the floating-point binary representation. (Remember we learned "implied one" format in the lecture) You need to type in the calculation steps or insert the picture of your handwriting using "insert" menu above.arrow_forward
