Converting a bit stream to binary

[ridd]

Hi I have some code that is supposed to take an array of booleans and for each (int minBits = 10) bits turn the binary number into decimal. The algorithm is working in part, but the bit at binArr[64] where when is somehow changing in between when I print the whole bit sequence in the first part of the code, and then when I use it to set the bool called bit in the second part of the code.

Can anyone see how this bit may be changing value...i'm completely baffled!

Thanks. Tom

// Convert each minBits segment into an int
for(int i = 0; i < 31; ++i)
{
printf("print arr %d:", i);
for(int j = 0; j < minBits; ++j)
{
if(fmod((double)j, minBits)==0 && j!=0 && j!=minBits*32)
{   printf(" ");    }
printf((binArr[i*minBits+j]==1)?"1":"0");
} // PRINTS CORRECTLY IN THE ABOVE CODE


printf("\r\nprint bit %d:", i);
unsigned int element = 0;
bool negative = binArr[i*minBits];
for(int j = minBits-1; j >= 0; --j)
{
bool bit = binArr[(i*minBits)+j];
// GIVES THE INCORRECT VALUE IN THE LINE ABOVE
printf((bit)?"1":"0");
//printf((binArr[i*minBits+j]==1)?"1":"0");
if(bit)
{
unsigned int bitval = pow(2, (double)(minBits-1-j));
element += bitval;
}
}
printf("\r\n");
uncompressed[i+1] = (negative)?element*(-1):element;
}
