Should I use long long or int64_t for portable code?
WebOct 9, 2013 · Remember it's signed int now. addr= (1 (0)x31). addr is of unsigned long type (64 bit) so to do the assignment righ value is converted to long int. Conversion from signed int to long int make addr (1)x33, (0)x31. And that's what being printed after all of thos converstions you weren't even aware of: 0xffffffff80000000. WebNov 1, 2024 · If you know that unsigned long on your platform is 64 bit, just use unsigned long instead of uint64_t. But be sure that you really meant that each field (such as a second) is 16 bits (2 bytes) and not 8 bit (1 byte). – nos Nov 1, 2024 at 20:37 Add a comment Your Answer Post Your Answer rowley ma urgent care
How do I bit shift unsigned long in C? - Stack Overflow
WebAug 12, 2024 · The bit rate refers to how many bits are transmitted per second. Bytes, on the other hand, are used to express storage sizes. 1 byte is equal to 8 bits. This means that one byte can represent 256 (2 8) different states. A byte is usually the smallest unit that can represent a letter of the alphabet, for example. WebMar 27, 2024 · Each hex digit requires 4 bits to represent. 32 * 4 = 128. (Note: your post says 36, but there are 32 digits there). The string itself, if you're talking about the text representation you've shown, is, as you say, encoding size dependent. In UTF-8, for example, that string is 36 * 8 = 288 bits long. Share. WebJul 6, 2024 · A decimal integer can be converted to binary by continually evenly dividing the integer by 2 (as in base ₂, as in binary) until the value reaches 0, reserving the resultant remainders in sequence as bits. When evenly dividing any number by 2, the remainder must be 0 or 1. Consider this example: Divide 21 by 2 until the result is zero. rowley ma town clerk
