Adjusted test values based on test reports where, the executing
platforms (LInux) had higher resolution for floating point numbers.

Example report:

Rounding the number could be a solution, but this is the responsibility
of this module IMHO
Adjusted documentation example (same numbers as in the test suite)
Prepping release 1.03
