<!-- --- title: "Netdata storage number" custom_edit_url: https://github.com/netdata/netdata/edit/master/libnetdata/storage_number/README.md --- --> # 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. [](<>)
