I am new to Microprocessor 8086. i should submit this assignment by monday evening. Can anybody help me with this question?

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.

Re: Need help with 8086 assembly language 80 80

post the code you are writing. Are you allowed to use the math coprocessor for log and other math functions ?

Re: Need help with 8086 assembly language 80 80

I would try using the FYL2X instruction, which computes:

st(1) = st(1) * log2(st(0)

Where log2 is logarithm to base 2. You can get from log base 2 to log base 10 with the formula:

log10(x) = log2(x) * log10(2)

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

Re: Need help with 8086 assembly language 80 80

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.
