Decimal Places and Show Fractions 

You can specify two display options for a numeric (or coupled numeric) attribute: the number of decimal places to use to display numeric values, and whether or not to display the first seven fractional powers of two (that is, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128) as fractions.

The Decimal Places property is a drop-down list. To specify the Decimal Places for a numeric attribute, select from the drop-down list of values between 0 and 6. The Show Fractions option is a standard Windows checkbox; click on it to toggle the setting on and off.

You can also use the menu commands as an alternative the Attribute Detail tab to specify these display options. (For more information, see Decimal Places and Show Fractions.)

The Show Fractions option only applies to units of measure that are traditionally displayed with fractional values (for example, inches) and is ignored for units that are not typically displayed with fractional values (for example, millimeters).

The Show Fractions option displays as fractions the fractional powers of two from 1/2 to 1/128 for absolute values between 0 and 100 (including all numerator values, such as 3/4, 5/16, and 27/64). The exceptions are for the units: (1) Horsepower in the dimension Power (Apparent) and (2) Cups, Pints, and Quarts in the dimension Volume, which for absolute values between 0 and 100 also display the “odd” fractions 1/3, 2/3, 1/5, 3/5, 4/5, 1/6, and 5/6, and approximately 130 fractions of the form “1/x” where ‘x’ ranges from 7 to 100 in increments of 1 (for example, 1/7, 1/15, and 1/78); from 100 to 1000 in increments of 50 (for example, 1/150, 1/250, and 1/500); and from 1000 to 2000 in increments of 100 (for example, 1/1100, 1/1200, and 1/1300).

A coupled numeric attribute allows you to specify settings for the number of Decimal Places and the Show Fractions option independently for each of the coupled dimensions.
