So the following program should put 23 into the my temp, compares 23 to 10 if it's smaller than 10 I can print otherwise put the temp away in rax, put 10 in r11 and divide 23 by 10. Put the result from rax in temp and check again. I still need to add a way to retrieve the earlier numbers but first thing first. Have I missunderstood what happens, the result I get

Why can't I copy a DLL from C:\\SysWOW64 from the command line?

If I try to copy a DLL file from C:\SysWOW32\ from the command line using copy on Windows 7 64-bit, I actually end up getting the file that's in C:\System32\ . Why is this happening? OK - dumpbin is able to differentiate the DLL files C:\Users\user\Desktop>dumpbin /headers C:\Windows\System32\opengl32.dll | grep machine 8664 machine (x64) C:\Users\user\Desktop>dumpbin /headers C:\Windows\SysWOW64\opengl32.dll | grep machine 14C

The callback just doesn't get called. I still can see incoming packages in the log: 08 - 02 15 : 48 : 57.985 : I / bt - hci ( 1051 ): btu_ble_process_adv_pkt 08 - 02 15 : 48 : 58.636 : I / bt - hci ( 1051 ): BLE HCI ( id = 62 ) event = 0x02 ) If I don't use the parameter to filter for UUIDs it works. We are using a manufacturer specific 128bit UUID for device of our company.

Why %processor_architecture% always returns x86 instead of AMD64

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am trying to retrieve the environment variable to detect whether the system is 32 or 64 bit. But on 64 bit server the environment variable %processor_architecture% is returning x86 instead of AMD64 . Does anyone has any clue about this? 回答1: You may be getting the wrong environment variable. If your application is a 32-bit application running on a 64-bit OS the process version of this environment variable will return x86. If you want to find the architecture of the machine, you can grab it from the following registry entry: HKEY_LOCAL

Or would a smart compiler such as GCC be able to actually deduce it? Edit: To make myself absolutely clear: I'm looking for a portable way to test for all the flags being set without explicitly testing each of

32-bit to 16-bit Floating Point Conversion

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I need a cross-platform library/algorithm that will convert between 32-bit and 16-bit floating point numbers. I don't need to perform math with the 16-bit numbers; I just need to decrease the size of the 32-bit floats so they can be sent over the network. I am working in C++. I understand how much precision I would be losing, but that's OK for my application. The IEEE 16-bit format would be great. 回答1: std::frexp extracts the significand and exponent from normal floats or doubles -- then you need to decide what to do with exponents that are

FLD instruction x64 bit

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have a little problem with FLD instruction in x64 bit ... want to load Double value to the stack pointer FPU in st0 register, but it seem to be impossible. In Delphi x32, I can use this code : function DoSomething(X:Double):Double; asm FLD X // Do Something .. FST Result end; Unfortunately, in x64, the same code does not work. 回答1: In x64 mode floating point parameters are passed in xmm-registers. So when Delphi tries to compile FLD X, it becomes FLD xmm0 but there is no such instruction. You first need to move it to memory. The same goes

(this is the only way we need for our project) So can any one help us to install/compile/modify the oracle instant client to make it work on Debian arm based system ?
