Byte to Integer and then to String conversion in Java
2016年4月8日 · Breaking down Integer.toString((bytes[i] & 0xff) + 0x100, 16).substring(1): Adding 0x100 (which is 256 decimal) sets the 9th bit to 1, which guarantees the binary number representation of the result has exactly 9-bits. You could equivalently do & 0x100. After setting bit 8, the result from the toString() will be 9 chars long (of zeroes and ones).
embedded - Fixed address variable in C - Stack Overflow
2009年3月28日 · When you reference 0x100, you are referencing system memory space, the same space the operating system is responsible for managing, and probably a very specific place that it monitors. The linker won't place code at specific memory locations, it works in 'relative to where my program code is' memory space.
I'm confused about this arithmetic operators - Stack Overflow
Therefore, we want the value to be 1 + the value pointed to by 0x100. This value is 0xFF, which is 255, so our sum is 256. This is hex 0x100, which becomes our value. subq %rdx, 8(%rax) The format of sub S, D instructions is D <- D - S. In order to work out the destination, we see that this is base + displacement. So it is 0x100 + 0x8 to give ...

Is the result of (new Uint8Array (1)) [0] = 0x100 undefined?
2014年2月17日 · is actually the same (a short-hand) as setting both array and result with the same value at the same time (the parenthesis does not matter as 0x100 is the one being evaluated and passed to result): var result = array[ 0 ] = 0x100; or expanded: array[ 0 ] = 0x100; var result = 0x100; so obviously result would in this case be 0x100 (256).
Sign extend a nine-bit number in C - Stack Overflow
2011年4月28日 · This tests the sign bit (the uppermost bit you are retaining, 0x100) and sets all the bits above it if the sign bit is set. You can extend this to 5 bits by adapting the masks to 0x1F , 0x10 and 0xFFE0 , being the lower 5 bits, the 5th bit itself and all the bits 5-16 respectively.
