---------------------------------------------------------------
Can you amend the description with a simple example of its operation? (Links go
stale.)
Include some key corner cases, e.g. does BITCOUNT(-1) return 32 or 64? Does
BITCOUNT(1.5) return 1 (same as BITCOUNT(1)) or 2 (same as BITCOUNT(3), which
is the shifted binary) or 4 (same as BITCOUNT(15), which is the shifted
decimal)?
