What could have caused this error?
 
integer value too large to represent
   while executing
"expr {round($val*(10.0**($decimals+3)))/(10.0**$decimals)}"
 
I know that "val" is a proper number and that "decimals" is 6.
 
I tried to run this expression with very high "val" values and could not
reproduce the error.

Are you *absolutely* sure that decimals is 6, because I can generate
the error via a smallish change to decimals:

    $ rlwrap tclsh
    % set val 123
    123
    % set decimals 999
    999
    % expr {round($val*(10.0**($decimals+3)))/(10.0**$decimals)}
    integer value too large to represent
    % set tcl_patchLevel
    8.6.12
