Lisp variable to round architectural measurements to nearest foot...

[brawleyman]

Hello! It's me again! Now that I have my macro figured out, I have a lisp that I am trying to tweak to give me only whole number measurements.

 

My lisp is a continued measurement tool that I use to estimate wire travel distances between devices and adds a user input value for drops. The lisp is set up for (rtos lensom 4 0) which gives me an output in architecural units and precision of whole inches. I know the "0" makes it round to the nearest inch, but I want to round to the nearest whole foot. Is there an extra variable I can include to do this or how should I approach it? Thanks!

maybe this...

(fix (atoi (rtos (/ lensom 12.0) 2 0)))

Hmm...I get

 

error: bad argument type: numberp: nil

 

when I add that to my lisp. What does that mean?...

 

Oh, wait a sec. At first it wasn't working, but I looked again and the "lensom" was supposed to be "lensum". Sorry I typed it wrong in my first post. Here is the solution...

 

(rtos (/ lensum 12) 2 0))

 

This works exactly the way I wanted it to. Thanks so much AGAIN lpseifert!

Sorry about the "quote". I couldn't find the "#" to put in my code, but just realized that I have to be the full editor instead of quick reply to do it. Sorry. I am getting the hang of it here.
