[Perl] Split lines into array - variable line items - variable no of lines.
Hi,
I have the following lines that I would like to see in an array for easy comparisons and printing:
Example 1:
Example 2:
So, the number of lines, the number of fields and the field order can differ.
As output I would like to see:
Those to be printed fields and values are always present, independent from the number of fields and the field order.
And field1 and value1 are always on the first place.
The background is that has to run on different systems and those different systems will deliver different field numbers and field order.
I started with something like this, but got stuck somehow due to a lack of Perl knowledge.
Would it have been a more static input then I it would be a bit more easier.
I would appreciate any kind of assistance.

fuzzy
math::fuzzy(n) Tcl Math Library math::fuzzy(n)
__________________________________________________________________________________________________________________________________________________NAME
math::fuzzy - Fuzzy comparison of floating-point numbers
SYNOPSIS
package require Tcl ?8.3?
package require math::fuzzy ?0.2?
::math::fuzzy::teq value1 value2
::math::fuzzy::tne value1 value2
::math::fuzzy::tge value1 value2
::math::fuzzy::tle value1 value2
::math::fuzzy::tlt value1 value2
::math::fuzzy::tgt value1 value2
::math::fuzzy::tfloor value
::math::fuzzy::tceil value
::math::fuzzy::tround value
::math::fuzzy::troundn value ndigits
_________________________________________________________________DESCRIPTION
The package Fuzzy is meant to solve common problems with floating-point numbers in a systematic way:
o Comparing two numbers that are "supposed" to be identical, like 1.0 and 2.1/(1.2+0.9) is not guaranteed to give the intuitive
result.
o Rounding a number that is halfway two integer numbers can cause strange errors, like int(100.0*2.8) != 28 but 27
The Fuzzy package is meant to help sorting out this type of problems by defining "fuzzy" comparison procedures for floating-point numbers.
It does so by allowing for a small margin that is determined automatically - the margin is three times the "epsilon" value, that is three
times the smallest number eps such that 1.0 and 1.0+$eps canbe distinguished. In Tcl, which uses double precision floating-point numbers,
this is typically 1.1e-16.
PROCEDURES
Effectively the package provides the following procedures:
::math::fuzzy::teq value1 value2
Compares two floating-point numbers and returns 1 if their values fall within a small range. Otherwise it returns 0.
::math::fuzzy::tne value1 value2
Returns the negation, that is, if the difference is larger than the margin, it returns 1.
::math::fuzzy::tge value1 value2
Compares two floating-point numbers and returns 1 if their values either fall within a small range or if the first number is larger
than the second. Otherwise it returns 0.
::math::fuzzy::tle value1 value2
Returns 1 if the two numbers are equal according to [teq] or if the first is smaller than the second.
::math::fuzzy::tlt value1 value2
Returns the opposite of [tge].
::math::fuzzy::tgt value1 value2
Returns the opposite of [tle].
::math::fuzzy::tfloor value
Returns the integer number that is lower or equal to the given floating-point number, within a well-defined tolerance.
::math::fuzzy::tceil value
Returns the integer number that is greater or equal to the given floating-point number, within a well-defined tolerance.
::math::fuzzy::tround value
Rounds the floating-point number off.
::math::fuzzy::troundn value ndigits
Rounds the floating-point number off to the specified number of decimals (Pro memorie).
Usage:
if { [teq $x $y] } { puts "x == y" }
if { [tne $x $y] } { puts "x != y" }
if { [tge $x $y] } { puts "x >= y" }
if { [tgt $x $y] } { puts "x > y" }
if { [tlt $x $y] } { puts "x < y" }
if { [tle $x $y] } { puts "x <= y" }
set fx [tfloor $x]
set fc [tceil $x]
set rounded [tround $x]
set roundn [troundn $x $nodigits]
TEST CASES
The problems that can occur with floating-point numbers are illustrated by the test cases in the file "fuzzy.test":
o Several test case use the ordinary comparisons, and they fail invariably to produce understandable results
o One test case uses [expr] without braces ({ and }). It too fails.
The conclusion from this is that any expression should be surrounded by braces, because otherwise very awkward things can happen if you
need accuracy. Furthermore, accuracy and understandable results are enhanced by using these "tolerant" or fuzzy comparisons.
Note that besides the Tcl-only package, there is also a C-based version.
