Details:

The elapsed time as displayed by toc incorrectly reuses the formatting of the
previous displayed number:

~:1> exp(9)
ans =  8103.1
~:2> tic;sleep(pi);toc
Elapsed time is 3 seconds.

or even

~:3> tic;sleep(4*pi);toc
Elapsed time is 1e+01 seconds.

Displaying a number with more digits after the decimal point helps:

~:4> exp(10)
ans =  2.2026e+04
~:5> tic;sleep(4*pi);toc
Elapsed time is 12.57 seconds.

Note that the number really has to be displayed:

~:8> exp(9)
ans =  8103.1
~:9> exp(10);
~:10> tic;sleep(4*pi);toc
Elapsed time is 1e+01 seconds.


Workaround: disp(toc)
