Approximate a % value

Dear community,
I have a log like this:

Code:

02:08:2012:15:00|machine1|    1543523|        234|     1658097|    230529                            
02:08:2012:15:00|machine2|    1415015|        193|     1530636|    210628                            
02:08:2012:16:00|machine3|    1282335|        244|     1407936|    199936                            
02:08:2012:16:00|machine1|    1427341|        198|     1550801|    218483                            
02:08:2012:16:00|machine2|    1256311|          0|     1366949|    176091

Now I calculated the % between 3rd and 4th fields, so I used the following::

Code:

cat server.log |   sed -e "s/\|//g" | awk '$7=100-($3*100)/($3+$4) {print $1,$2,$7"|",$3,$4,$5,$6}'

...and the response is:

Code:

02:08:2012:15:00|machine1| 1543523| 99.9859| 234| 1658097| 230529 
02:08:2012:15:00|machine2| 1415015| 99.9874| 193| 1530636| 210628 
02:08:2012:16:00|machine3| 1282335| 99.9827| 244| 1407936| 199936 
02:08:2012:16:00|machine1| 1427341| 99.9872| 198| 1550801| 218483 
02:08:2012:16:00|machine2| 1256311| 100| 0| 1366949| 176091

And that's should be ok.

What I need now, is approximate the output % (the variable $7) in something like:

Code:

99.988   => 99.988 
99.9894 => 99.989
100      => 100
99.9      => 99.900

Please help, I'm scratching my head to find a solution.! Smilie

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
