floating point variables korn shell

Hi I'm not using Korn93 but want to use floating point variable.
Is there any solution to do that ?

thx for help.

---------- Post updated at 02:28 PM ---------- Previous update was at 12:38 PM ----------

I have the following peace of code:

Code:

for n in `cat log.January.1.array`
do
       (( number=`print $n | awk -F\; '{print $1}'` ))
      (( filesSize=$filesSize+$number ))
done
 
print "Files size equals : $filesSize"
   
   
(( nrOfIterations=$filesSize/200000 ))
print "Estimated iterations number is: $nrOfIterations"


if (( nrOfIterations>0 ));
then
      (( nrOfIterations=$nrOfIterations+1 ))
      print "Real iterations number is: $nrOfIterations"
      print
fi

Problem is how to distinguish value round this value to sections : ?
1.1-1.5 this should be equal to 1
1.6-1.9 this should be equal to 2

thx for help

I solved it.
Solution below :

Code:

for n in `cat log.January.1.array`
do
       (( number=`print $n | awk -F\; '{print $1}'` ))
      (( filesSize=$filesSize+$number ))
done
 
print "Files size equals : $filesSize"
   
   
(( nrOfIterations=$filesSize/200000 ))
print "Estimated iterations number is: $nrOfIterations"


if (( nrOfIterations=0 ));
then
      (( nrOfIterations=$nrOfIterations+1 ))
      print "Real iterations number is: $nrOfIterations"
      print
else
      (( nrOfIterations=$nrOfIterations+1 ))
      print "Real iterations number is: $nrOfIterations"
      print
fi

print.ini

print.ini(5)							File Formats Manual						      print.ini(5)

NAME

       print.ini -- survex printer settings

Description
       The print.ini file contains printer descriptions for the Survex printer drivers.

   File Format
       The  format  of the print.ini file is similar to the .ini files used on Microsoft Windows.  The file is divided into sections, each section
       corresponding to a separate printer description.  A section starts with a section name in square brackets,  e.g.  aven's  built-in  printer
       support uses the aven section:

       [aven]

       followed by some options of the form <option>=<setting>, e.g.:

       font_size_labels=6

       In the supplied print.ini each option is preceded by a comment (indicated by a semicolon ';') briefly explaining the option.

Customising Printer Settings
       If you wish to change the size of the font used for labels or the colours used you need to override some of the setting in print.ini.

       You  shouldn't  modify  the master print.ini (located in /usr/share/survex on Unix, or in the same directory as the Survex program files on
       other systems), or your changes will be overwritten by upgrades.  Instead create:

	  o  /etc/survex/print.ini (Unix - system-wide settings)

	  o  ~/.survex/print.ini (Unix - per user settings)

	  o  myprint.ini in the directory where Survex is installed (other platforms)

       If one of these files contains a setting then aven will use it instead of the setting in the master print.ini.  Any settings not  specified
       will still fall back to the values in print.ini.
