Shell Programming and Scripting

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

thx for help.

I have the following peace of 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 :

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

Exactly what shell are you using?

I don't know exactly.
How can I read this info in solaris ?

If you are on Solaris, you are probably using a custom version of ksh88. In this case you will have to use the bc utility to perform floating point arithmetic.
