Subject: dmm: vc870: show display value properly in debug output
X-Git-Tag: libsigrok-0.4.0~38
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=b89462e45706e9b4f65eced96c7d76347f4b5569;p=libsigrok.git

dmm: vc870: show display value properly in debug output

It was confusing to see the display value (5 digits) printed in debug
output as a float. Print it the same way as shown on the real device,
without comma, of course.
This also allows to simplify the code a little.
