However, if I go into Properties..Build and set the "Platform Target" to "x86", it won't compile. I need "x86" because I need to reference some .dll's that simply won't work if I choose "All Platforms". ----- start error ----- System . BadImageFormatException : Could not load file or assembly 'file:///D:\backtest\C#\WCF service\WcfServiceLibrary\bin\Debug\WcfServiceLibrary.dll' or one of its

Right now everything is implemented in C++ in x64 mode, using native 64-bit ints. That limits me to x<2^64~1.8*10^19. I want to go further, to do that, I need a library that does 128-bit arithmetic. And it has to be very fast. In particular, integer divisions should be fast. Otherwise I'll be sitting here waiting for the results till

So my question is why can’t I move 8 bit variable into much larger 16 bit register ? I have already referred this , this and this OP but it does not answer my question. NOTE: I am using emu8086 assembler I am new to assembly language so I apologise if it's a stupid question. 回答1: why can’t I move 8 bit

The question is, how does one convert a 5- or 6-bit channel to 8 bits? The obvious answer is to shift it. I started out by writing this: puts ( "P6 320 480 255" ); uint16_t buf ; while ( read ( 0 , & buf , sizeof buf )) { unsigned char red = ( buf & 0xf800 ) >> 11 ; unsigned char green = ( buf & 0x07e0 ) >> 5 ; unsigned char blue = buf & 0x001f ; putchar ( red

I am using Eclipse 3.5 SE on Ubuntu 9.04 Jaunty. How can I resolve this error? 回答1: I had same problem with Oracle Java 7 and Eclipse on 32-bit system. libswt-gtk-3.6-java and libswt-gtk-3.6-jni were already installed. What helped : cd ~/.swt/lib/linux/x86 ln -s /usr/lib/jni/* . Maybe this can be done reconfiguring Java alternatives or what. 回答2: I believe Mikolaj Lechtanski's workaround is more

How can this be done? 回答1: Try this: #include #include int main() { std::bitset x(23456); std::cout (23456) 回答2: I have an int that I want to first convert to a binary number. What exactly does that mean? There is no type "binary number". Well, an int is already represented in binary form internally unless you're using a very strange computer, but that's an implementation detail -- conceptually, it is just an integral number. Each time you print a number to the screen, it

I want both 32 bit and 64 bit applications to be able to use "my_shared_library". How can I have both 32 bit and 64 bit programs use "my_shared_library"? I was thinking I would either have to have 2 versions of "my_shared_library" or maybe there is some way at run-time to pick the correct 32bit/64bit nuget package of "non_anycpi_dependency" based on the run-time bit

My inputs are in Q1.31 (both) format. input1 = A32 (Ah Al) - higher, lower half's of A32 input2 = B32 (Bh Bl) - higher, lower half's of B32 Result should be in Q1.31 format, leave the overflow case I need C code for the above. Please provide the explanation with formats also. 回答1: Signed Q1.31 format is a fully fractional format capable of representing operands between -1 and almost +1. The scale factor is 2 31 . This means that when each Q1.31 operand is stored in a

AND XOR NOT OR 回答1: Bit fields (flags) They're the most efficient way of representing something whose state is defined by several "yes or no" properties. ACLs are a good example; if you have let's say 4 discrete permissions (read, write, execute, change policy), it's better to store this in 1 byte rather than waste 4. These can be mapped to enumeration types in many languages for added convenience. Communication over ports/sockets Always
