Re: How to convert binary to BCD ?

Why 26 bit ? Cant represent more than 26 bit numbers ? Is Reason for limit ,for 32 bit output? :idea: The maximum number which can show in 26-bits is (2 26 - 1) = 67108863 There are 8 digits which needs 8 nibbles of 4 bytes. Now consider (2 27 - 1)... it is 134217728 and it has 9 digits. It needs 9...

Re: How to convert binary to BCD ?

I think this is stupid problem.. BCD is about representing each digit of a decimal number in a nibble (4-bits). A 26-bit number can be represented with 4 bytes. 2 26 - 1 = 67108863 This has 8 digits. If I represent this in BCD, 3 - 0011 6 - 0110 8 - 1000 8 - 1000 0 - 0000 1 - 0001 7 - 0111 6 - 0110...

How to do profiling easily on C++ (timing of functions)

C standard library provides clock() function, which can be used to measure the elapsed time. It is a system independent C function declared in time.h (compatible on most operating systems), but it does not give accurate results, not even millisecond accuracy. In order to see the accuracy of clock(),...

Fix Xperia Mini ST15i Overheating/Capacitive Buttons Issue

So you bought a SE Xperia Mini and you have overheating issues with the phone. This is a known issue, but there is no fix in the latest update by Sony. I’ve read they have a calibration fix at the authorized service center, but on visiting they asked me to wait for a week. Sorry I love my phone and ...

Re: Upload zip folder, extract it, rename files inside it, save

Opps. I have just seen that you needed further help on this.Thought you have fixed it by yourself after my first tip. I have tried to re-read your code and I have seen few problems. One of the problems I see in your code is, you have defined function "findexts" within "if(isset($_FILES['fupload'])) ...

Re: Upload zip folder, extract it, rename files inside it, save

I see a semantic issue (bad programming) there in your code. Can you change your function function openZip($file_to_open) to function openZip($file_to_open, $target) and remove the global definition from there. So when you call the function, you call it alone with the target. Can you do that change ...
