Recently in C++ code I came across the notation 1 << 8. At first, I thought it was just a standard bitshift, till an explanation of the code told me it was fixed point notation, something I had not heard of till then. I have tried to read up about fixed point notation, but am still confused about it. As far as I can tell, the code was using a 16 bit integer, where the first 8 bits were used for something completely different than the last 8, and thus 1 was shifted up 8 bits. But, I have no clue exactly what value this would be or how to find it given the number.
