 Synopsis:          Interval Arithmetic
+Description:
+    A 'Numeric.Interval.Interval' is a closed, convex set of floating point values.
+    .
+    This package is careful to manage the rounding direction of each floating point
+    operation to ensure that the resulting interval is conservative. Effectively the lower bound of each computation is always rounded down, and the upper bound is rounded up.
