This gem provides a way to calculate uncertainties of measurements.
5.129213.pm(0.01).to_s #=> "5.13"
You can access the value and delta fields:
5.129213.pm(0.01).value #=> 5.129213 5.129213.pm(0.01).delta #=> 0.01
Error propagation is handled for operations
3.2.pm(0.1) + 4.5.pm(0.1) # => 7.7.pm(0.2) 3.2.pm(0.1) * 4.5.pm(0.1) # => 14.4.pm(0.77)
