you have to 'escape' it:
echo 'SCCS=33.4' | sed 's/\./\\\&/g'

On the second thought, why don't you do everything in AWK? You already are using it, so..

Code:
nawk -F= -v mult=10 '{ $2 = sprintf("%.1f", $2 * mult); print }' $FILE

lessecho

LESSECHO(1)						      General Commands Manual						       LESSECHO(1)

NAME

       lessecho - expand metacharacters

SYNOPSIS

       lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ...

DESCRIPTION

       lessecho  is  a program that simply echos its arguments on standard output.  But any metacharacter in the output is preceded by an "escape"
       character, which by default is a backslash.

OPTIONS

       A summary of options is included below.

       -ex    Specifies "x", rather than backslash, to be the escape char for metachars.  If x is "-", no escape char is used and  arguments  con-
	      taining metachars are surrounded by quotes instead.

       -ox    Specifies "x", rather than double-quote, to be the open quote character, which is used if the -e- option is specified.

       -cx    Specifies "x" to be the close quote character.

       -pn    Specifies "n" to be the open quote character, as an integer.

       -dn    Specifies "n" to be the close quote character, as an integer.

       -mx    Specifies "x" to be a metachar.  By default, no characters are considered metachars.

       -nn    Specifies "n" to be a metachar, as an integer.

       -fn    Specifies "n" to be the escape char for metachars, as an integer.

       -a     Specifies that all arguments are to be quoted.  The default is that only arguments containing metacharacters are quoted
