For some files, when scanning with -p all, I get true preak values that are (slightly) less than the sample peak values:

Loudness, LRA, Sample peak, True peak, True peak
-26.0 LUFS, 7.4 LU, 0.294945, 0.294944, -10.6 dBTP, p1.wav
-23.8 LUFS, 7.6 LU, 0.418935, 0.418934, -7.6 dBTP, p2.wav
-20.6 LUFS, 10.6 LU, 0.904647, 0.904645, -0.9 dBTP, p3.wav

In my understanding, this runs counter to the idea of a “true” peak value. But perhaps it is just a problem of different rounding rules?
