binary

问题 assuming I have a function to manually calculate decimal from binary number *up to four characters(binary) *assuming you can only input 0 and 1 character below code works perfectly function bin_to_dec($bin) { $bin = str_split($bin); $bin = array_reverse($bin); $i = 0; $dec = 0; foreach($bin as $values) { $ans = $values * pow(2, $i); $dec += $ans; $i++; } return $dec; } $bin = 1010 //4 $bin = 1 //1 $bin = 0 //0 assuming if you cannot use function strrev(), str_split(), array_reverse(), how

问题 This question is for a deeper understanding of my previous question about large size Canvas animation. The question is here: Repeat HTML canvas element (box) to fill whole viewport I am trying to understand the logic behind the TypedArray - Uint8ClampedArray. I will first start with my research and get to the question itself later. So, ImageData represents the pixel data of the HTML5 Canvas. It allows for much faster performance and is good for heavy animations. After we have our ImageData

问题 I've been trying to read the binary file with Java, and the binary file is written in C#. And some of those data is contain a DateTime data. When DateTime data will be written into the file (in binary), it using DateTime.ToBinary(); on C#. For reading the DateTime data, it will convert first from bytes into long data, using BitConverter.ToInt64(byte[], 0) , and then convert it again from long into DateTime data using DateTime.FromBinary(long) . (All of those are written in C#). Let's say the

问题 i have an assignment that asks to define 4 integers, each of a different byte length (1, 2, 4, 8) would this code work? segment .data one db 1 two dw 01 four dd 1011 eight dq 01101110 global _start _start: mov rax, [one] ; mov rbx, [two] ; im also curious if i can safely store these values into registers to be used for addition in the future. I'm supposed to use sign extension for the shorter values, but could use some direction 回答1: You're writing constants in decimal. If you want the digits

问题 I have a table of time and binary values, > head(x,10) Time binary 1 358.214 1 2 359.240 1 3 360.039 0 4 361.163 0 5 361.164 1 6 362.113 1 7 362.114 0 8 365.038 0 9 365.039 0 10 367.488 0 I want to check after a second wether the value in binary column is 1 or 0, and then create new column of the new values. The time here is not continues. For example, first value here is (358.214) and the binary value is 1, if I add a second it is going to be (359.214) and the value is still 1 based on the
