i think I spoke too soon with this one. it appears the numbers aren't adding up.

i was using the below code:

Code:
awk 'BEGIN {total=0}{for(i=1;i<=NF;++i){total+=$i}} END {printf "%.2f\n",total}'

but it looks like its not adding up the numbers correctly.

i should mention that the numbers with the echo quotes are expected to change. meaning, there can be 5, 10, 400 numbers that needs to be added up.

Code:
echo "5.3 3.4 43.5 etc" | awk 'BEGIN {total=0}{for(i=1;i<=NF;++i){total+=$i}} END {printf "%.2f\n",total}'

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
