You can set the format and the number of decimal places to be used when you enter and display linear and angular units.
You can choose from several common conventions to represent the format and the precision of linear distances and coordinates displayed in the Properties palette, dynamic input, the status bar, and other locations.
For example, here are three variations of dynamic input.
You can specify that positive values of angles are measured either clockwise or counterclockwise, and the direction of angle 0 (usually East or North). You can enter angles using grads, radians, or surveyor's units or using degrees, minutes, and seconds.
If you use surveyor's angles when specifying polar coordinates, indicate whether the surveyor's angles are in the north, south, east, or west direction. For example, to enter the relative coordinates for a property line that is 72 feet, 8 inches long with a bearing of 45 degrees north, 20 minutes, 6 seconds east, enter @72'8"<n45d20'6"e.
Understand Rounding and Precision
When you specify the display precision of units, the values for coordinates and distances are rounded off. However, the internal precision of coordinates and distances is always maintained regardless of the display precision.
For example, if you set the display precision of decimal-format units to 1 (or 0.0), the display of coordinates is rounded to one place after the decimal point. Thus, the coordinates 0.000,1.375 are displayed as 0.0,1.4, but the internal precision is still maintained.
