I am trying to track a variable in a subgraph but after hours of going around in circles I cannot resolve why a subgraph value cannot be set to a specific value. That value is 20231211 but it always overflows to 20231212!! No matter how I code it see attached code. As you can see three subgraphs being set to 20231211 in the code but the subgraph value always has 20231212. Even -20231211 doesn't work. Is this a bug?? SCSFExport scsf_TestSubgraph(SCStudyInterfaceRef sc) { SCSubgraphRef DayNumber = sc.Subgraph[0]; SCSubgraphRef SecondNumber = sc.Subgraph[1]; SCSubgraphRef ThirdNumber = sc.Subgraph[2]; if (sc.SetDefaults) { sc.GraphName = "Test"; sc.AutoLoop = 1; DayNumber.Name = "Number"; DayNumber.DrawStyle = DRAWSTYLE_IGNORE; DayNumber.PrimaryColor = RGB(0, 206, 206); SecondNumber.Name = "SecondNumber"; SecondNumber.DrawStyle = DRAWSTYLE_IGNORE; SecondNumber.PrimaryColor = RGB(0, 206, 206); ThirdNumber.Name = "ThirdNumber"; ThirdNumber.DrawStyle = DRAWSTYLE_IGNORE; ThirdNumber.PrimaryColor = RGB(0, 206, 206); return; } int testnumber = 20231211; DayNumber[sc.Index] = static_cast<float>(testnumber); SecondNumber[sc.Index] = 20231211.0; if (SecondNumber[sc.Index] != 20231211.0) { SCString BarDateTime = sc.DateTimeToString(sc.BaseDateTimeIn[sc.Index], FLAG_DT_COMPLETE_DATETIME); sc.AddMessageToLog(SCString().Format("%s - SecondNumber: %f", BarDateTime.GetChars(), SecondNumber[sc.Index]), 0); } ThirdNumber[sc.Index] = -20231211.0; } Have updated to latest version and tried on two different computers but still same result.

This is because the Sierra Chart Study Subgraph arrays, are 4 byte single precision floating-point value arrays. They do not have the precision to fully represent that number. If we go to 8 byte floats, then the memory use of Sierra Chart increases significantly. We have considered that, but there will be significantly increased memory use.
