# The following tests have results equivalent to Postgres (differences
# in string representation and number of decimals returned, but otherwise
# the same). These do not pass using the inf package. The inf package
# (http://gopkg.in/inf.v0) is what we used to use, but it had various problems
# (for example, all the test cases below), and was replaced with apd.
