Overview. For sensors like the VEX Ultrasonic sensor that return a range of values, we often simply want to check if the returned value is more than, equal to, or less than some value called a threshold. For example say that we have the sensor set up and are driving around, but we need to stay at least 5 inches (127 mm) away from any obstacles.
How do I tell excel to treat a  in an excel formula as a ? :) Excel reads quotation marks as signifying text inside, but my text field requires a  to be included in it as well, so I need to somehow tell Excel that the  is part of the text field within the two s :p. Does that make sense? Mike.
When you use a VLOOKUP formula you want an answer to something. What you want to return is what Excel calls the col_index_num (Column Index Number). In short: Which column in the data you want to return data from. When youâre looking for Nate Harris and find him in row 17 of the sample data, the column index number determines which column in the data the result will come from.
