Note  Some accounting programs display negative values with the negative sign (–) to the right of the value. To convert the text strings to values, you must return all of the characters of the text string except the rightmost character (the negation sign), and then multiply the result by –1. For example, if the value in cell A2 is "156–" the following formula converts the text to the value –156.
