Hi,

I calculate a duration by milliseconds by using:

"set dur [expr ([clock clicks -milliseconds] - $timeasked) * 0.001]"

that usually gives me a time like "64.409".

But on some networks (i.e. quakenet) i get times like "64.408999999999999".

How do i trim the number to three decimals?


thanks in advance,

tueb

Code:
set dur [format %.3f [expr {([clock clicks -milliseconds] - $timeasked) * 0.001}]]
