&DENOMD
Controls the lowest common denominator (LCD) of the fraction in all dual dimensions. the actual value of the dimension is rounded to the LCD, or an increment of the LCD, as the dimension is created.
For example, if the dimensioned distance in inches is actually 1.1265 and 8 is the specified LCD, the fraction displayed would be 1 1/8. However, if the actual distance was 1.502, the fraction displayed would be 1 1/2 since one half is a divisible unit of eighths.
