Rounding...

[Nate242]

What is the best way to round using autolisp? I'd like to be able to round to 3 places.

ex) 200.4955 -> 200.496

Are you trying to change a real to string? If so then you do something similar to this:
(rtos 200.4955 2 3) which is
(rtos number mode accuracy) mode is optional if your units are set to the desired output (i.e. scientific, decimal, engineering etc.)

Adding to lpseifert's post..

If you wante a real number as a result, use 'atof' on the rounded string returned by 'rtos'.
