[SOLVED] identify: ... Q16 ... HDRI

I find it confusing that identity, on an IM compiled with --enable-hdri, says Q16 in the first line and HDRI in the Features line.
Is there a reason for the Q16 in this situation?

Identify is accurate. The color pixels are float for HDRI, but its depth is still 16, meaning the values typically range from 0 to 65535 but unlike non-HDRI, pixel values are not rounded to unsigned integers.

HDRI also means that negative values are allowed.
