The text entities representing the numbers could have variable digits as per the input of a given file. If numbers are derived from lisp then Text may not have the numbers in desired precision. If the requirement is to display numbers with specific precision as per the project requirement, Change Precision lisp will be of help. There are 4 command prompts in this macro T1, T2, T3 and T4. T1 command will convert the text precision to 1 digit, T2 command will convert the text precision to 2 digits, so on and so forth.
Please refer free lisp to round off elevation values to nearest 0.005.
