Yes, try:
Code:
printf "%e\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )"


or, for example:
Code:
sci_bc() {
  printf "%e\n" "$(bc -l <<< "${1//[eE]/*10^}")"
}

sci_bc "$EV*$DV"

Its working well. Great help Smilie

Two more questions,

1. How can I store it in another variable?
2. I am able to see 5.000000e-04. How can I change it to specified format like 5.0E-04 (or) 0.0005 (or)5.00E-4 etc,??

Good to hear Smilie

1.
Code:
newvar=$(printf "%e\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )")

2.
Code:
$ printf "%e\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )"
5.000000e-04
$ printf "%.1E\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )"
5.0E-04
$ printf "%.4f\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )"
0.0005
$ printf "%.2E\n" "$(bc -l <<< "${EV/[eE]/*10^}*${DV/[eE]/*10^}" )"
5.00E-04
$
