I was wondering is there any availab开发者_StackOverflow中文版le bitwise operations for CUDA\'s vector types like int4/int2? I see lot of aux functions in cutil_math.h, but no any bit (left/right shif
I don\'t understand why this gives me the same answer: long long a = 3265917058 >> 24; std::cout << a << std::endl; //194
I have a top 10 list with a score (highest score wins) and a timestamp. The timestamp is used in the case of a tie score, in which case the tied score with the lowest timestamp wins (first person to
Basic Question:I have a k dimensional box.I have a vector of upper bounds and lower bounds.What is the most efficient way to enumerate the coordinates of the vertices?
I\'m very new to dealing with bits and have got stuck 开发者_高级运维on the following warning when compiling:
#define SwapByte4(ldat开发者_Go百科a) \\ (((ldata & 0x000000FF) << 24) | \\ ((ldata & 0x0000FF00) << 8) | \\
I read that Left shift e1<<e2 is equivalent to e1* 2e2. But for the code: x=5; printf(\"%d\",x<<3);
Apple sometimes uses the Bitwise-Shift operator in their enum definitions. For example, in the CGDirectDisplay.h file which is part of Core Graphics:
I am trying to figure out how exactly arithmetic bit-shift operators work in C, and how it will affect signed 32-bit integers.
So I have the following assembly language code which I need to convert into C. I am confused on a few lines of the code.
