Howdy, I have a DataRow pulled out of a DataTable from a DataSet. I am accessing a column that is defined in SQL as a float datatype. I am trying to assign that value to a local variable (c# float datatype) but am getting an InvalidCastExecption 

DataRow exercise = _exerciseDataSet.Exercise.FindByExerciseID(65); _AccelLimit = (float)exercise['DefaultAccelLimit'];

Now, playing around with this I did make it work but it did not make any sense and it didn’t feel right. 

_AccelLimit = (float)(double)exercise['DefaultAccelLimit'];

Can anyone explain what I am missing here?
