Subject: [Bluez-devel] Elimination of pow() in SBC code
Date: Sun, 28 Nov 2004 00:51:46 +0100 [thread overview]
Message-ID: <1101599506.18467.6.camel@pegasus> (raw)
Hi Henryk,
the pow() function is the only reason for linking with -lm and it is
only used in one place with a limit range of parameters.
scalefactor[ch][sb] = pow(2.0, (frame->scale_factor[ch][sb] + 1));
So what is the range of scale_factor[ch][sb]. From a quick testing a saw
that it ranges from 0 - 15. Is this always true? If yes, then I would
use a pre-calculated array for 2^x.
Regards
Marcel
