Since you're using awk anyway, do everything in awk, because it supports floating point variables. Use awk's return status to tell the shell loop whether it finished.

Incidentally, since you're using awk, you don't need grep either, since awk can do the function of both.

Code:
while symclone -sid XXX -f Clone_test query | awk -v R="$y" '/MB/ { printf("%s/%s remaining\n", $2, R); exit($2 > $y)}'
do
        sleep 10
done

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
