Match SWINTEGERS and saturation print format

The documentation for SWINTEGERS did not match the accuracy of printed
floating numbers, and this lead to a rare possibility for test failures,
exemplified by test_slgof.py::test_slgof_hypo where it was possible to
end up with two saturation points being printed identically.

The usage of SWINTEGERS in test code has been tuned accordingly.
