What it is for
The small letter d. Its capital is D at 68, exactly 32 lower — the difference is bit 5, which is why case conversion is a bitwise operation.
Where the number comes from
The alphabet was placed so that capitals start at 65 and lowercase at 97 — exactly 32 apart, a single bit. Changing case is therefore c ^ 32, and this was a deliberate design decision rather than a coincidence.
