# title: Negative infinity (double) shown incorrectly without sign in isql
# decription:
# Bug was in ISQL. We do insert in the table with two DP fields special values which
# are "-1.#INF" and "1.#INF" (at least in such view they are represented in the trace).
# These values are defined in Python class Decimal as literals '-Infinity' and 'Infinity'.
# After this we try to query this table. Expected result: "minus" sign should be shown
# leftside of negative infinity.
#
# Confirmed WRONG output (w/o sign with negative infinity) on 3.0.3.32756, 4.0.0.690.
# All fine on:
# 3.0.3.32794: OK, 1.235s.
# 4.0.0.713: OK, 1.203s.
