Note that the output you said you want on lines starting with "Value One" does not match the sample data you provided.

Akshay's proposal comes close to what I think you want, but doesn't print the results with leading + signs and five decimal places.

Try:
Code:
awk -v Variable='54.24425 35.24535 24.24225 35.24535' '
BEGIN { split(Variable, vlist) }
$1 == "Value" {
        $4 = sprintf("%+.5f", vlist[++v] - $3)
        $3 = vlist[v]
}
1' file1.text > file2.txt

which puts the following into file2.txt:
Code:
Data 1
Value One 54.24425 +29.99999
Value Two 35.24535 -10.00000

Data 2
Value One 24.24225 -20.00000
Value Two 35.24535 +10.00000

I believe the values shown in red are correct, but do not match the output you said you wanted.

If you want to run this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.
