Far Cry review 24 25 (4/30/2005 3:25:05 PM) comp.sys.ibm.pc.games.action I know I'm a bit late to be reviewing this since it came out a little while ago, but I'm only just getting around to it. 1. This is so *incredibly* derivative. I've seen it all before. Mad scientist condu... Richard

Getting intermediate results in 64 bits 14 21 (4/6/2005 4:10:25 PM) comp.lang.c Hi, Using GCC on my G4, if I have a calculation like this: #include uint64_t a = 0xffff * 0xffff ; the result will be clobbered to 32 bits because that's the length of an integer. How do I keep all the i... Richard

How to get 64-bit intermediate results 4 35 (4/6/2005 7:49:54 AM) comp.lang.c++ Hi, If I'm doing something like this: #include uint64_t i = (0xffff * 0xffff ) ; Or indeed any arbitrarily long expression, how do I ensure the intermediate results won't be truncated to 32 bits without pu... Richard

Fastest sort algorithm? 3 21 (3/31/2005 2:20:40 PM) comp.lang.c++ Hi, I have a structure of 3 16-bit values. I have either 65000, 256000 or 1 million instances of this structure. I want to sort the lot of them according to the number contained in one of the fields. Dupl... Richard

Is a const parameter generally optimized to a reference? 7 19 (3/16/2005 8:45:48 AM) comp.lang.c++ Hi, The point of using const on a parameter to a function should be to let your compiler know that the parameter shouldn't be modified during your program. This allows you to keep your code safe and bug-fre... Richard

Using vector units 3 27 (3/11/2005 3:21:53 PM) comp.lang.c++ Hi, Many processors have some kind of facility for working on multiple data at once (MMX, SIMD, SSE2, Altivec, Velocity Engine, etc). What's the state of the art with regards trying to use these with C/C++?... Richard

Assignment from scalar to user-defined type 2 30 (3/6/2005 7:22:32 AM) comp.lang.c++ #include class uint128bit { public: uint64_t bits0to63; uint64_t bits64to127; uint128bit operator= (uint128bit op2) { bits0to63 = op2.bits0to63; bits64to127 = op2.bits64to127; return *this; } uint1... Richard

printf a 64-bit number 3 39 (3/2/2005 7:56:48 AM) comp.lang.c++ GCC 3.3, XCode: #include #include int main (int argc, char * const argv[]) { uint64_t a=10123123123LL; printf("%d\n", a); std::cout << a; std::cout << "\n"; return 0; } The printf statement gives me ... Richard

using uint64_t with GCC 4 32 (2/27/2005 12:13:15 PM) comp.lang.c++ uint64_t i64_BitMask = (uint64_t) (1 > 32); printf ("BitMask %x\n", a); This produces ffffffff. I'm pretty sure, watching the stages in debugging, that 1 << 33 is resolving to zero, since it's being shifted... Richard

Preprocessor log()? 2 30 (2/27/2005 2:56:31 AM) comp.lang.c Hi, I want to do something like this: const int a = "283529"; const int b = log to base 2 of a; and have it *at compile time*. ... Richard

Does bool true always == 1? 10 27 (4/4/2005 8:26:02 AM) comp.lang.c++ Does standard c++ define "true" to be always equal to 1? My code: int num = 1 + (value1== value2); Can I be certain that "num" will ALWAYS be either 1 or 2? How about on a Windows machine? ... AlabamaWins (5)

power - novice 12 20 (4/4/2005 9:16:46 PM) comp.lang.c++ I just want to raise a number to a power. e.g.: 16^2 The pow()-function of cmath seems to be not enough. I've read about valarray. Is it really so difficult? Can you give me an example. Thanks Roman ... roman.toengi1 (24)
