Q1 Write an 8086 assembly language program that will compute:

2.0 * log10 X for x = 0.1, 1.0, 10.0, 100.5, 1000.0, and six other values using a loop. All values are in the single-precision (short real) format.

Kindly help me. I am breaking my head like anything

Pls Help me in doing this?

Write a program that will input a positive integer and print out the list of its prime factors. Comment on the run time of your algorithm and state any limitations that you have imposed on the input integers

Actually int 21h function 2 will only display the single ascii character contained in dl. It will not output an entire string, and still less convert a floating point number into a string and then output it.

Beginners in assembly language always think that they are still programming in a high level language. Writing a procedure to convert a floating point number to a string, and then display it, is not a job I would particularly want, and I am not new to assembly language.
