Please help in this regard

actually why do you need an array in this situation ?
variable 'total' itself will do right ?

sorry this is not a reply..
but pl tell me how i can post my querries on the forum?

yes mani we can even do with variable total itself. But if we want to do it with an array it is not going why ? please try solve my problem..

What shell are you using ?
The first line of your script that should tell it is missing.

i m using bash shell

$bash --version

GNU bash, version 3.00.16(1)-release (sparc-sun-solaris2.10)

I don't think bash supports floating point arithmetic.

ksh (at least ksh93) does it fine.
