   Although `netdata` does all its calculation using `long double` (128 bit) arithmetics, it stores all values using a **custom-made 32-bit number**. This custom-made number can store in 29 bits values from -167772150000000.0 to  167772150000000.0 with a precision of 0.00001 (yes, it is a floating point number, meaning that higher integer values have less decimal precision) and 3 bits for flags (2 are currently used and 1 is reserved for future use). This provides an extremely optimized memory footprint with just 0.0001% max accuracy loss (run: `./netdata --unittest` to see it in action).
