tcl foreach - integer?

[Marco Faggella 2]

Silvia, Frank, users

why does tcl treat my parameters as integers when I use foreach? the result of the expression epsc0 returns zero instead of 0.00195

foreach {fc Es } {
31 31736 ....
set epsc0 [expr 2*$fc/$Ec]

how can I evaluate that rational while keeping using foreach?

thanks

... ok

I added .0 and it works

31.0 31736.0
