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.
Important points to remember about Excel formulas: 1  formulas in Excel always begin with the equal sign 2  ( = ); the formula is always typed into the cell where you want the answer to appear; 3  the subtraction sign in Excel is the dash 4  ( - ); the formula is completed by pressing the Enter key on the keyboard.
