Summary: expr return value

Initial Comment:
In Tcl 8.5.4:

% expr 0.8 - 0.35
0.450000000000007
%expr 0.6 - 0.15
0.449999999999996

In Tcl 8.4:

% expr 0.8 - 0.35
0.45
%expr 0.6 - 0.15
0.45

OS is Linux.

So scripts that used to work in 8.4 fail in 8.5.4 for our customers.

Is there a fix for this issue? workaround?

Thanks,

Israel Taller
