Comment (by torquil@…):

 Thanks, that seems very likely. So it is the intentional lower default
 precision of std::cout that makes it print 0.05, which is an approximation
 to the actual variable value. And it would in fact add those zeroes and
 the final nonzero digit if its precision was increased sufficiently using
 setprecision().

 But I guess std::cout uses a lower default precision intentionally, and
 perhaps the same should at least be considered for the program_options
 printout.

 So it seems that this is just an esthetic problem, and can even be changed
 using the second argument as you stated, so I will simply let it print the
 value that it does at the moment. The extra digits don't bother me much.
