The letters refer to the datatypes as listed at Reference card | kdb+ and q documentation – Kdb+ and q documentation (kx.com) . b = boolean, i = int etc.
The domain is the data type of the input and the range is the data type of the output. So if you give it a boolean you get an int, if you give it a real or float you get a real or float back etc. GUID, char and symbol are marked with a dot to indicate that these types are not supported.
