Topic: truncated sum

[danadrian.baluta@yahoo.co]

Hello,

I don't remember seeing this before.
If i try

Code - Auto/Visual Lisp: [Select]

1. (+ 500000.0 123.234)

i get
500123.0

If I do the same thing with the CAL command in AutoCAD, i get 500123.234.

How can I get Autolisp to not truncate the sum?

Thank you,
Adrian

Change LUPREC system variable to 4. Or use smth like this:

Code - Auto/Visual Lisp: [Select]

1. (rtos (+ 5e5 123.234) 2 14)

Thank you for the answer.

LUPREC doesn't seem to influence this. It was set to 8.
I tried your trick and it works. But it needed the real number, not the text.
So i decided to give it a go with the truncated numbers. I needed to draw a polyline with these numbers.
To my surprise, the coordinates were correct, with all the decimal places. So it's just a matter of displaying them truncated, not actually truncating them.
Weird.

Thanks,
Adrian

The real value is 500123.234 - you can check it:

Code - Auto/Visual Lisp: [Select]

1. (* (+ 5e5 123.234) 1e3)
