Rounding issues with sc.FormattedEvaluate

I have some unexpected rounding issues while using sc.FormattedEvaluate. int Match = sc.FormattedEvaluate(StudyArray[sc.Index], sc.BaseGraphValueFormat, EQUAL_OPERATOR, StudyArray[sc.Index-1], sc.BaseGraphValueFormat) ? 1 : 0;
I am comparing current index float values from a SubGraph Array with values of the same Array one index back. sc.BaseGraphValueFormat in my ChartSettings is 0.01. When I check the output of the above code there are matches when it should not match and vice versa. Some example output: //did match but shouldn't StudyArray = 2343.473633, PastStudyArray = 2343.475342, Match = 1 | 2017-02-19 14:50:55 * //should match but didn't StudyArray = 2342.526855, PastStudyArray = 2342.534180, Match = 0 | 2017-02-19 14:45:43 * StudyArray = 2343.485840, PastStudyArray = 2343.492188, Match = 0 | 2017-02-19 14:56:30 * //these should all match, only the first does StudyArray = 2343.488525, PastStudyArray = 2343.492188, Match = 1 | 2017-02-19 14:57:14 * StudyArray = 2343.486328, PastStudyArray = 2343.492188, Match = 0 | 2017-02-19 14:57:14 * StudyArray = 2343.485596, PastStudyArray = 2343.492188, Match = 0 | 2017-02-19 14:57:14 * |

The way that this works is if the two values are within each other half of 0.01 which is .005, then they are considered equal. We will make sure the documentation makes this clear. If you want to accomplish what you want you would have to round the values first to the nearest .01 with sc.RoundToIncrement.
