Hi! So I have a problem with binary numbers. If I take -77 (decimal number) as an example and want to convert it into a binary number and a two's complement in a bit length of 8, I proceed as follows: I turn the -77 into the 77 for myself. This gives me the binary…
Hey guys! Unfortunately, I have absolutely no idea how to calculate with two's complement numbers. In particular task 1.6, tasks a) and b). For me it doesn't make sense how to calculate this, especially in b). The left and right numbers are both already two's complement. How am I supposed to subtract them? I hope…
I want to represent the decimal number 10 in two's complement. My approach would be 0000 1010. I'm not sure though, since only negative numbers start with 1.
For x – y. Which relation >, >=, <, <=, =, not equal must be set, at x – y so that N = V and Z = 0 N = V N not equal to V N not equal to V or Z = 1 are met
Z = 1, meaning the zero flag is set. When does the zero flag become 1, if the last operation results in 0? E.g., the overflow V apparently plays no role here, since it isn't specified. The calculation is always x – y. Therefore, x must be identical to y 4 – 4 = 0,…
Hi guys, I want to convert the decimal number 44 into a binary number "4 bit number range with negative numbers". According to my calculations I get the binary number 101100, but since I only have 4 bits left to store the result is 1100, is that correct or do I have to subtract the…
Hey guys, 1:How can I convert the binary number 11010 (5-bit number range with negative numbers) into decimal? 2: convert the decimal number -13 in the (5 bit number range with negative numbers) into the corresponding binary number? Would be nice if someone could explain this to me, mfg
Hey. I'm currently preparing for my computer science exam and I'm stuck on ones' and two's complement… can you help me? I already have the first two lines, but the rest doesn't make sense. LG Jonathan
I don't understand why the result is 107 and not -149, because 107 would again be in the range: -127,…,128.
Task: Calculate 111 2 − 110 2 by adding the numbers. First, convert the numbers to 4-bit two's complement and express the result in 4-bit two's complement and decimal. Are the carry or overflow flags set? If so, what is their significance in the context? Solution:
I have to calculate -6 + 4 -6 would be in 6 bit two's complement = 111 001 (since 6 would be 000110) and 4 would be 000100 Added together that would be: 0010100 or? And then 11+5 11= 001011 5= 000101 added = 010000 or?
