Let me explain better. I have this values:

Code:
res=0.0032
res1=0.41234
res2=0.42342
res3=0.4523
res4=0.23123
res5=0.12311

and i want to do a for so that i can get the values inside this variables:
Code:
c=6
maximo=$res
for (( c=$total-1; c>=0; c-- ))
do
if [ $maximo <= $res$c ];            
then
maximo=$valores
fi
done

But what when i do that it put the value of res just shows the value of the value res with the value of c in the front

I solved it. I done something like this:
Code:
maximo=$res
########################################
for (( c=5; c>=0; c-- ))
do
variavel=res$c 
varx=${!variavel}
echo $varx
if(( $maximo <= $varx ));            
then
maximo=$valores
fi
done

do
  eval "var=\$res$c"
  maximo=$(echo $var $maximo | awk '{print ($1>$2?$1:$2)}')
  c=$(( $c - 1))
done

echo $maximo
