This option allows the user to specify the number of decimal places of precision to be displayed for the calculated(i.e. Output) point.
For example, if the user is converting to a Geodetic (i. e. Lat/Long) coordinate system and specifies “3” for display precision, the result will be displayed with three decimal places of precision.
Example:
Assume the user has chosen to display the Angular Unit Format as DD MM SS.
N 45 30 22.123
W 110 23 46.123
CAUTION: If this result is used to ‘back calculate’ the coordinate to the INPUT coordinate system, there MAY be a loss of precision (READ: the position may shift due to rounding errors).
If multiple conversions are needed, it is best to specify a higher number of decimal places. More decimal does not imply greater accuracies; it just reduces ‘rounding’ errors in the calculations.
