# This file implements regression tests for SQLite library. The focus of

# SQLite library. Failures of tests in this file are related to the
# ext/misc/totype.c extension.
#
# Several of the toreal() tests are disabled on platforms where floating
# point precision is not high enough to represent their constant integer
# expression arguments as double precision floating point values.
