Command Line return wrong value.

Check this out in your Autocad command line:

(setq num 12.123456)

And here is the result:

12.1235

Why is that ? ... it's not return the same number which is 12.123456

And I tried to inserted into a text, and it come like this:

(vl-cmdf "text" pause "" "" num)

12.12345600000000

The sysvar LUPREC controls the decimal accuracy that is displayed on the screen. It doesn't change the value of the variable, just the display mode.

You do need to keep in mind the ACAD REALs are limited to 15 significant places. I think LUPREC is still limited to 8 places. So when comparing REALs, look into the (equal) function in lieu of (=). -David

If you are interested in retrieving the value as a string, then do something like this:

(rtos num 2 16), which in your example should return "12.1234560000000"
