+# Netdata storage number
+
+Although `netdata` does all its calculations using `long double`, 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's a floating point number, meaning that higher integer values
+have less decimal precision) and 3 bits for flags.
+
+This provides an extremely optimized memory footprint with just 0.0001% max accuracy loss.
