I wanted to do this at first but you can achieve the same effect by
truncating the output, if you're lucky. But you can cook up your own
luck:

If the correct answer is 3.14159265354 and you want epsilon=3D~0.001 you
would be tempted to write 3.142 except that if another program makes
an error of -0.000093 it'll show the wrong digit. So to make your own
luck, you either twiddle it so that epsilon=3D~0.0001 and show four
digits, or keep ~0.001 but make the correct answer 6.2831853072.
