The floating point precision in bits
Note that changing this only affects newly computed quantities.
Old values stored in variables are obviously still in the old
precision and if you want to have them more precise you will have
to recompute them. Exceptions to this are the system constants
Should the precision setting be remembered for the next session. If unchecked, either the default or any previously saved setting is used each time Genius starts up. Note that settings are saved at the end of the session, so if you wish to change the default check this box, restart genius and then uncheck it again.
