This error should be a simple one but I cant seem to make it work. The problem lies in the fact that this very same code works earlier in the program. I don's see any reason for it to be sending an error on this instance and not the four previous ones. Reference the code below, and feel free to provide any criticism you may have as it sh...
In our project, we take two floats from the user, store them in integer registers, and treat them as a IEEE 754 single precision floats, manipulating the bits by masking. So after I multiply the 23 bits of fraction value, should I take into account the result placed in the LO register if I want to return a single precision float (32 bits...
I have 3 columns in my db table, I need to multiply column, itm_count & itm_price and output the total for a given id(itm_id).
SELECT sum(itm_price * itm_count) as total FROM ods_temporder WHERE itm_id='11'
I tried to do this using the above sql query, but the result was null. What seems to be the issue here?

In my mips assembly code, I used the multi instruction to multiply 2 large numbers since the result could not fit in one register. This means that the number is saved in the hi and lo special registers. My problem is how do I print the result of the multiplication. I can access hi and lo and put them in other registers (i.e. $t0, $t1)...
I'm working on a micro-controller without hardware multiply and divide. I need to cook up software algorithms for these basic operations that are a nice balance of compact size and efficiency. My C compiler port will employ these algos, not the the C developers themselves.
My google-fu is so far turning up mostly noise on this topic.

Is it possible to multiply a char by an int?
For example, I am trying to make a graph, with *'s for each time a number occurs.
So something like, but this doesn't work
char star = "*";
int num = 7;
cout << star * num //to output 7 stars
...
The following code fails to compile
#include <iostream>
#include <cmath>
#include <complex>
using namespace std;
int main(void)
{
const double b=3;
complex <double> i(0, 1), comp;
comp = b*i;
comp = 3*i;
return 0;
}
with
error: no match for ‘operator*’ in ‘3 * i’
What is wrong here, why cannot I multiply w...
If I do the following:
int c0 = CHAR_MAX; //8 bit
int c1 = CHAR_MAX; //8-bit
int i = c0*c1; //store in 32-bit variable
printf("%d\n", i); //prints 16129
We can see that there is no problem with to 8-bit numbers being multiplied together, and producing a 32-bit output.
However, if I do
int i0 = INT_MAX; //32-bit
int i1 = INT_MAX; //3...
I wanted to know how the processor does multiplication in a multi-cycle data-path right from the beginning i.e from Instruction Reading -> decoding the instruction-> reading register files etc.
In other word I wanted to know that given the booth's algorithm for multiplication implemented separately (a circuit is given) how will you ext...
