getting the average of a list of decimals.
Whats up fellas, I am new here... just wanted to see if anyone knew a way to get an avergage of a list of numbers... I am trying to use bc (number of records in file divided by sum of all records in file) but it is not giving me accurate data.
IE:
------------------------------------------------------------
COUNT=`wc -l $datafile | awk '{print $1}'`
SUM=`sumfld $datafile 2 | awk '{print $NF}' #sumfld is internal utilty to add contents of datafile's feild
AVG=`echo "$SUM / $COUNT" | bc`
-------------------------------------------------------------
I find that if the $COUNT=2, and $SUM=9.99, $AVG should be be about 4.995, but instead it just returning 4. Any help would be appreciated.

NAME
Xmark - summarize x11perf results
SYNTAX
Xmark datafile
DESCRIPTION
Xmark is a shell script that reads the indicated datafile and compiles a benchmark which it writes to standard output. It writes three
numbers:
A weighted performance number for the x11perf results.
A weighted performance number for a standard SparcStation 1, with SunOS 4.1.2, X11R5 Xsun, and a CG3 dumb Color Frame Buffer.
The Xmark, which is the ratio of the two numbers above.
The datafile must be an ordinary file, produced by x11perf in the following way:
x11perf -display display -v1.3 -rop GXcopy GXxor -all > datafile
It is possible to run the GXcopy and GXxor tests separately, as long as they are concatenated to the same output file:
x11perf -display display -v1.3 -rop GXcopy -all > datafile
x11perf -display display -v1.3 -rop GXxor -all >> datafile
or
x11perf -display display -v1.3 -rop GXxor -all > datafile
x11perf -display display -v1.3 -rop GXcopy -all >> datafile
