# ozo,Average!

The \$b variable is from the Infile,this statement: runt1!9!14(The 2nd value,it can be 3values or 5values or 9values)
Infile:
runt1!9!14
runt2!9!14
runt3!9!15
runt4!9!25
runt5!9!3

Then How do i calculate my average of the values for each parameter and print the average value to the end of each line(See output file) in the output file e.g
-9.960116E+02!+1.002406E-03!
means that -9.960116 is to the power of 2,1.002406 is to the power of -3.

ps:Your codes did not include this calculation of the power to 3?It only sum up the total is it?

Output file(Contains only 2values but it can be 3 or 5 or 9 values):

s1!NE2 40/40 Vth0!+9.939227E+02!+9.982348E+02!avg(value calculated)!
s2!NE2 40/40 Vth0!-9.960116E+02!+1.002406E-03!avg(value calculated)!

s1!Vth Vb/2.5!+3.985872E-08!+3.948130E-08!avg(value calculated)!
s2!Vth Vb/2.5!+3.974027E-08!+3.971276E-08!avg(value calculated)!

Below is my codes:
open(FILE1,"infile") || die "Can't open infile because \$!";
open(FILE2,">outfile") || die "Can't open outfile because \$!";

while( <FILE1> )
{
(\$a,\$b,\$c) = split(/!/);
\$c = sprintf("%02d",\$c);
open (FILE3,"<\$a") || die "Can't open \$a because \$!";
while( <FILE3> )
{
next unless /SYS_WAFERID!\$c\b/.../SYS_WAFERID!\$c\b/;
next unless (\$para,@values) = (/([^!]+)!.*!/,/!([-+][-+\d.E]+)/g);
push @para,\$para unless \$para{\$para};
if(\$b == 3)
{
for('s1'..'s3')
{
push @{\$para{\$para}{\$_}},shift @values;
}
}
if(\$b == 5)
{
for('s1'..'s5')
{
push @{\$para{\$para}{\$_}},shift @values;
}
}
if(\$b == 9)
{
for('s1'..'s9')
{
push @{\$para{\$para}{\$_}},shift @values;
}
}
}
close FILE3;
}
for \$p ( @para )
{
if(\$b == 3)
{
for \$s ('s1'..'s3' )
{
print FILE2 join"!",\$s,\$p,@{\$para{\$p}{\$s}};
\$avg =0;
for(@{\$para{\$p}{s}})
{
\$avg = \$avg + \$_;
}
\$avg/=@{\$para{\$p}{\$s}};
print FILE2 "!\$avg!\n";
#print FILE2 "\n";
}
print FILE2 "\n";
}
if(\$b == 5)
{
for \$s ('s1'..'s5' )
{
print FILE2 join"!",\$s,\$p,@{\$para{\$p}{\$s}};
print FILE2 "\n";
}
print FILE2 "\n";
}
if(\$b == 9)
{
for \$s ('s1'..'s9' )
{
print FILE2 join"!",\$s,\$p,@{\$para{\$p}{\$s}};
print FILE2 "\n";
}
print FILE2 "\n";
}
}

How do i solve my problem of getting !avg(0)!
Pls help,thanks!!
