1This class is a container class for numbers with a number of associated
2symmetric and asymmetric errors. It overloads practically all common
3arithmetic operations and trigonometric functions to propagate the errors.
4It can do proper scientific rounding (as explained in more detail below in
5the documentation of the significant_digit() method).

7You can use Math::BigFloat objects as the internal representation of
8numbers in order to support arbitrary precision calculations.
9
10Errors are propagated using Gaussian error propagation.

12With a notable exception, the test suite covers way over ninety percent of
13the code. The remaining holes are mostly difficult-to-test corner cases
14and sanity tests. The comparison routines are the exception for which
15there will be more extensive tests in a future release.
