Subject: Do not require signed zero support in ldexp tests()
X-Git-Tag: upstream/0.1.0~1788^2~3^2~10^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1e44f197ded674677381f65c840820728cf36efb;p=platform%2Fupstream%2FVK-GL-CTS.git

Do not require signed zero support in ldexp tests()

This relaxes ldexp() tests to allow -0/+0 to be interchanged.
