Do you need that just for customization or for other specific reasons?

It's not complicated to explain but it's quite annoying to implement. Have you tried my example in a comment to Sean's asnwer fprintf('\b %f',3)?
ans =
...
Is a message displayed (or printed) in the command window. To display something different from the standard behaviour requires you to use some specific functions that allow customization.
However, these functions (sprintf and fprintf) are not so flexible to adapt automatically to every situation while a consistent implementation of the customization would require to preserve the root formatting and to discriminate between variable types.
Thus you need to check the variable type and the root format, then you need to decline your customized formatting for each combination of the two above.

fprintf('\b %f',3)
This option obviously doesn't consider the get(0,'format') in use and the type of variable.
Thus, as Walter says, it is possible but would require quite some coding, which honestly IMO is in general not justified (and specifically in this case, since the OP did not motivate the use of it).

It is possible in theory: you can overwrite the method named "display". Which can be a big nuisance to do, but it is possible.

You can fake it by using "input('>> ', 's'); disp('ans = '); eval(S), input('>> ', 's');". I cannot check this currently, but it should look like a real command line output.
