You can use printf to format the number to 2 decimal places and include thousand separators:
Code:
USED_DB=$( printf "%'.2f" $USED_DB )
USED_PC=$( printf "%'.2f" $USED_PC )

---------- Post updated at 17:16 ---------- Previous update was at 17:13 ----------

From printf manual:
Code:
A block size specification preceded by `'' causes output sizes to be
displayed with thousands separators.  The `LC_NUMERIC' locale specifies
the thousands separator and grouping.  For example, in an American
English locale, `--block-size="'1kB"' would cause a size of 1234000
bytes to be displayed as `1,234'.  In the default C locale, there is no
thousands separator so a leading `'' has no effect.

basename(1)							   User Commands						       basename(1)

NAME
basename, dirname - deliver portions of path names SYNOPSIS
/usr/bin/basename string [suffix] /usr/xpg4/bin/basename string [suffix] dirname string DESCRIPTION
The basename utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan- dard output. It is normally used inside substitution marks (``) within shell procedures. /usr/bin The suffix is a pattern defined on the expr(1) manual page. /usr/xpg4/bin The suffix is a string with no special significance attached to any of the characters it contains. The dirname utility delivers all but the last level of the path name in string. EXAMPLES
Example 1: Setting environment variables The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and the environment variable MYMAILPATH to the string /home/sms/personal: example% NAME=`basename $HOME/personal/mail` example% MYMAILPATH=`dirname $HOME/personal/mail` Example 2: Compiling a file and moving the output This shell procedure, invoked with the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current directory: example% cc $1 example% mv a.out `basename $1 .c` ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of basename and dirname: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: /usr/bin +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ /usr/xpg4/bin +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWxcu4 | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
