reading double from binary file in c

Question

hi, can anyone show how to correctly convert binary represented data into double value in C. for example, i have 8 unsigned char values to be converted to double value (let's name it buffer). so buffer[0]'s 0's bit is LSB, and buffer[7]'s 7's bit is MSB. thanks a lot in advance!

Answer 1

Just cast it, I think

char buf[8];
double x;
...
x = *((double*) buf);
