1 00:00:02,940 --> 00:00:04,470 Hey, guys, what's up? 2 00:00:04,770 --> 00:00:10,920 So in the last video, we learn how those two numbers are stored, how those are stored and how my floating 3 00:00:10,920 --> 00:00:12,060 point numbers are stored. 4 00:00:12,440 --> 00:00:15,330 So in this video, we will learn how negative numbers are stored. 5 00:00:16,500 --> 00:00:21,990 For example, I have four bytes of memory space and here's my data. 6 00:00:23,160 --> 00:00:29,100 I want to find what is the largest and what is the smallest number that I can store. 7 00:00:29,520 --> 00:00:32,190 I want to find the value of A and B. 8 00:00:33,180 --> 00:00:37,980 OK, so for simplification, let's say let's say I have four bids. 9 00:00:38,510 --> 00:00:39,680 That is half a bite. 10 00:00:40,100 --> 00:00:44,780 So I want to find the value of A and B for four bids. 11 00:00:45,680 --> 00:00:45,960 OK. 12 00:00:46,560 --> 00:00:51,100 So, OK, so what does the largest number that I can store. 13 00:00:52,190 --> 00:00:55,700 Obviously when, when, when and when that is plus seven. 14 00:00:56,480 --> 00:01:01,290 And what is the smallest number that I can store and for. 15 00:01:02,030 --> 00:01:05,330 Zero zero zero and zero net is zero. 16 00:01:06,130 --> 00:01:06,350 OK. 17 00:01:06,770 --> 00:01:12,740 So if I followed this presentation, the maximum value that I can store is plus seven and the minimum 18 00:01:12,740 --> 00:01:14,630 value that Igen stories zero. 19 00:01:17,130 --> 00:01:17,380 OK. 20 00:01:25,840 --> 00:01:32,060 But there's a very major problem with this approach, and the problem is we have never done. 21 00:01:32,170 --> 00:01:35,520 But also we have minus 10, we have minus eight. 22 00:01:35,540 --> 00:01:36,640 We have minus seven. 23 00:01:37,000 --> 00:01:38,370 We need negative number also. 24 00:01:38,710 --> 00:01:40,240 So how does two negative numbers. 25 00:01:40,600 --> 00:01:42,460 So let us talk about the first approach. 26 00:01:45,630 --> 00:01:50,930 OK, so the first upload sees what is the difference between then and minus 10? 27 00:01:53,050 --> 00:01:58,990 This is the only difference you will see and be right then and they will put a negative sign. 28 00:02:00,570 --> 00:02:00,730 OK. 29 00:02:00,890 --> 00:02:03,800 So what do we do if I if I have four kids? 30 00:02:06,490 --> 00:02:14,170 I will use my first word as a sign, but if it is when my number is negative. 31 00:02:14,590 --> 00:02:23,350 If it is zero, my number is positive and remaining, Tibbits will be used to find magnitude. 32 00:02:26,170 --> 00:02:32,050 Okay, so in this way, our problem will be resolved and we can and we will be able to represent negative 33 00:02:32,050 --> 00:02:32,830 numbers also. 34 00:02:33,370 --> 00:02:36,580 Okay, so let's see what is the largest and what is the smallest number. 35 00:02:38,510 --> 00:02:40,210 So for finding the largest number. 36 00:02:40,660 --> 00:02:41,670 I have four bids. 37 00:02:42,610 --> 00:02:44,560 First of all, I just number will be positive. 38 00:02:44,620 --> 00:02:49,740 So the first bid will be zero and the remaining three bid all will be won. 39 00:02:49,900 --> 00:02:51,370 To maximize the magnitude. 40 00:02:51,730 --> 00:02:58,100 So this is plus seven means positive and religious. 41 00:02:58,220 --> 00:03:00,370 My list number two can store. 42 00:03:01,370 --> 00:03:03,920 So I have four bids for a small listener. 43 00:03:04,010 --> 00:03:04,760 But what will I do? 44 00:03:05,150 --> 00:03:12,370 I will make my first bid when that is negative number and I will maximize the manged. 45 00:03:12,590 --> 00:03:14,210 That is when, when and when. 46 00:03:15,050 --> 00:03:16,700 So this is seven. 47 00:03:16,970 --> 00:03:18,230 My number is negative. 48 00:03:18,560 --> 00:03:21,050 So this is a business minus seven. 49 00:03:22,380 --> 00:03:23,430 Now, what is our range? 50 00:03:24,630 --> 00:03:31,020 Our ranges from minus seven to plus seven. 51 00:03:31,770 --> 00:03:34,890 So obviously this approach is much better than our previous approach. 52 00:03:35,460 --> 00:03:35,760 Why? 53 00:03:36,180 --> 00:03:39,910 Because in this approach, we are able to store negative numbers also. 54 00:03:40,860 --> 00:03:43,200 But there's a problem with this approach also. 55 00:03:43,230 --> 00:03:44,160 And what is the problem? 56 00:03:45,180 --> 00:03:49,740 OK, so tell me, what does this number. 57 00:03:51,120 --> 00:03:51,910 So zero means? 58 00:03:51,930 --> 00:03:53,190 My number is positive. 59 00:03:53,730 --> 00:03:55,560 And this represent zero. 60 00:03:55,590 --> 00:03:57,630 So my number is plus zero. 61 00:03:58,800 --> 00:04:02,850 Now tell me, what is this number? 62 00:04:03,660 --> 00:04:06,270 So one means my number is negative. 63 00:04:06,660 --> 00:04:08,700 And this represent magnitude. 64 00:04:09,000 --> 00:04:11,980 So my number is minus zero. 65 00:04:13,560 --> 00:04:19,230 So you can see here there are two representation of zero zero and minus zero. 66 00:04:19,700 --> 00:04:19,900 OK. 67 00:04:20,220 --> 00:04:23,120 So there is ambiguity in the representation of zero. 68 00:04:23,580 --> 00:04:24,910 And we will resolve it. 69 00:04:25,560 --> 00:04:26,820 So how we can resolve it. 70 00:04:27,510 --> 00:04:28,350 What we will do. 71 00:04:29,280 --> 00:04:30,720 OK, so how we can resolve it. 72 00:04:31,140 --> 00:04:31,770 What we will do. 73 00:04:31,800 --> 00:04:35,900 We will do some minor changes for positive, no representation. 74 00:04:36,690 --> 00:04:39,350 We will follow the above approach that is signed. 75 00:04:39,350 --> 00:04:42,320 But the first word will be used to assign it. 76 00:04:42,420 --> 00:04:45,180 And the remaining bits will be used as magnitude. 77 00:04:48,080 --> 00:04:48,670 So positive. 78 00:04:48,810 --> 00:04:49,780 No representation. 79 00:04:49,940 --> 00:04:52,790 I will use the above approach for negative numbers. 80 00:04:52,910 --> 00:04:55,370 We have something called to complement. 81 00:04:58,970 --> 00:05:00,070 Those compliment form. 82 00:05:00,560 --> 00:05:00,840 OK. 83 00:05:01,040 --> 00:05:04,630 So negative numbers are represented in those compliment form. 84 00:05:05,480 --> 00:05:06,770 Now, what is to this compliment? 85 00:05:08,440 --> 00:05:12,500 So it does compliment is actually once compliment. 86 00:05:16,840 --> 00:05:24,760 Plus, when and how to find device complement, which is very simple, you just flip all the bits, 87 00:05:26,560 --> 00:05:31,860 flip all the bits of a tiny number, and what you will have is called Wendt's complement. 88 00:05:32,530 --> 00:05:34,140 OK, so let's see some example. 89 00:05:36,390 --> 00:05:38,670 For example, I want to store minus two. 90 00:05:39,900 --> 00:05:40,770 So what do we do?
