Consider this:
% scan "0.00001" %f a
% set a
1e-5
Is it possible to get a numeric representation out of scan like 0.00001?
Changing tcl_precision does not change the result format.

% format %f $a
0.000010
% format %1f $a
0.000010
% format %1.5f $a
0.00001
see man n format.

Actually, 1e-5 is an example of a very common numerical representation.
As Uwe notes, you can use [format] to change the default representation,
more accurately, change the string representation of the number.
(This form is chosen on the basis of a set of heuristic rules, since you
did not specify how you wanted the number to be converted to a string ;))
