Question

Do not have to show work, only need the final answers in hexadecimal.

6. Determine the hexadecimal representation (Ninteger=8, Nfractional=8) of: (a) 49.335937500 (b) 121.957031250 (c) 19.917968750 (d) -105.605468750 (e) -89.402343750 (f) -31.390625000

Answer 1

To convert a decimal number into hexadecimal number we can either use the direct method for the indirect method of conversion. In direct method the decimal number is directly converted into hexadecimal by dividing the decimal number by 16 and noting the remainder in down to up direction. The indirect method first converts the decimal into binary or octadecimal form and then it is converted into hexadecimal.

The final answer in hexadecimal from decimal after conversion is shown below:

a) 49.335937500= 31.56

b) 121.957031250=79.F5

c) 19.917968750=13.EB

d) -105.605468750=-69.9B

e) -89.402343750=-59.67

f) -31.390625000=-1F.64
