I want to convert a string into a signed int. Following is the requirement. I have stored hex value as a string in buffer. Now I want to convert that value into signed int. buf = "fb869e" Convert this into signed int. So o/p should be -293218. but when I'm trying to convert using strtol I'm getting 16483998. So what I should I do? ...
The ISO C standard allows three encoding methods for signed integers: two's complement, one's complement and sign/magnitude. What's an efficient or good way to detect the encoding at runtime (or some other time if there's a better solution)? I want to know this so I can optimise a bignum library for the different possibilities. I plan ...
Hi there, Actually I've (probably) a "simple" problem. So I don't know how to cast a signed integer to an unsigned integer. My code : signed int entry = 0; printf("Decimal Number : "); scanf("%d", &entry); unsigned int uEntry= (unsigned int) entry; printf("Unsigned : %d\n", uEntry); If I send the unsigned value to the console (see...
I know the WAV file format uses signed integers for 16-bit samples. It also stores them in little-endian order, meaning the lowest 8 bits come first, then the next, etc. Is the special sign bit on the first byte, or is the special sign bit always on the most significant bit (highest value)? Meaning: Which one is the sign bit in the WAV ...
Say I read these bytes: "6F D4 06 40" from an input device. The number is a longitude reading in MilliArcSeconds format. The top bit (0x80000000) is basically always zero and is ignored for this question. I can easily convert the bytes to an unsigned integer: 1876166208 But how do I convert that unsigned value into its final form of 3...
I am learning computer arithmetic. The book I use(Patterson and Hennessey) lists the below question. Write mips code to conduct double precision integer subtraction for 64-bit data. Assume the first operand to be in registers $t4(hi) and $t5(lo), second in $t6(hi) and $t7(lo). My solution to the answer is sub $t3, $t5, ...
At first glance, this question may seem like a duplicate of http://stackoverflow.com/questions/199333/best-way-to-detect-integer-overflow-in-c-c, however it is actually significantly different. I've found that while detecting an unsigned integer overflow is pretty trivial, detecting a signed overflow in C/C++ is actually more difficult ...
say,I've a domain abc.com,I've made a self signed SSL Certificate successfully for www.abc.com,(even *.abc.com),however it doesn't work for abc.com how to fix this issue? ...
What is the formatter to make sure that + or - signs are always shown in front of the float value in printf() in C? I haven't done C in a while, so where can I find a good reference on the web, any suggestions are appreciated ...
Guys, I have a value thats 5 bits in length. 4 bits determine the number and the 5th bit determines the sign, there by holding any value between -16 and +15. How can I accomplish sign extending from a constant bit width in C#? I know in C, I can use something like the follow to accomplish this: int x; // convert this from using 5 bits ...
I'm just learning OpenMP from online tutorials and resources. I want to square a matrix (multiply it with itself) using a parallel for loop. In IBM compiler documentation, I found the requirement that "the iteration variable must be a signed integer." Is this also true in the GCC implementation? Is it specified in the OpenMP standard? If...
