This property is applicable to display units related to feet and fractional inches:
- DUT_FEET_FRACTIONAL_INCHES
 - DUT_RISE_OVER_FOOT

When SuppressLeadingZeros is true:
- If the foot component of the value is zero (the value is less than one foot), it will not be displayed. For example, 0' - 2 3/4" will be displayed as 2 3/4".
 - If both the foot and integer inch components of the value are zero (the value is less than one inch), neither will be displayed. For example, 0' - 0 3/4" will be displayed as 3/4".
 - However, an integer inch component of zero will be displayed if the foot component is non-zero. For example 1' - 0 3/4" will be displayed as 1' - 0 3/4".
