Subject: amixer: fix print_dB for -0.99 .. -0.01 range
X-Git-Tag: v1.0.27.2~3
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=c80a38dbf53531d57c9bd4ccdc05553bd7fb79a1;p=alsa-utils.git

amixer: fix print_dB for -0.99 .. -0.01 range

The first number is 0 when input dB (hundreds) is in range -99 .. -1 .
The printed number was positive in this case. This patch fixes this issue.
