Subject: About integer64
Date: Thu, 09 May 2002 10:10:10 +0200	[thread overview]
Message-ID: <3CDA2EE2.A3C6D824@alsa-project.org> (raw)


I don't think that's a bad thing to have support for 64 bit integers
(perhaps for future use, who knows), but I think that to use this to
store a fixed point float is a big mistake.

If you think for it you realize that it's *not* an integer and
applications are betrayed in their expectation.

I see two possible solutions:
1) convert internal representation to float (or double) and add support
for this type of data
2) use SNDRV_CTL_ELEM_TYPE_BYTES

As I've already said I prefer 1) but too 2) is far better that to have a
wrong use of a data type.
