Hello there,
I'm converting floating to real-world data values with the code snippet below.
I notice that after scaling, floating point values are no longer fractional, implying that data loss has occurred.
Thank you in advance
fi(linspace(-5,5,10),true,32,28)
storedInteger(fi(linspace(-5,5,10),true,32,28))
storedInteger(fi(linspace(-5,5,10),true,32,28)) / 2 ^28
I'm expecting fractional length, but I'm wondering where it's gone. Thanks !!

You forgot to take into account that an integer data type operated on with a double precision number, returns the integer data type
fi(linspace(-5,5,10),true,32,28)
SI = storedInteger(fi(linspace(-5,5,10),true,32,28))
class(SI)
SI / 2^28
double(SI) / 2^28
