Description INOMATA Kentaro 2014-01-31 06:27:25 UTC
From http://d.hatena.ne.jp/hnw/20140104

decimal dcm1 = 987654321098765432109876543.25m;
decimal dcm2 = 987654321098765432109876543.25999m;

unlike dcm1, dcm2 should be converted to 987654321098765432109876543.3 because a result is NOT equally close to two representable values, but actual value is 987654321098765432109876543.2.
