Topic: issues with x,y extraction and alteration coding, please help.

[alanjt]

Code: [Select]

(setq base_point (getpoint "\nSpecify base point: "))
(setq ptascii_x (car base_point))
(setq ptascii_x (rtos ptascii_x 2 2))
(setq ptascii_y (cadr base_point))
(setq ptascii_y (rtos ptascii_y 2 2))
(setq point_calc (rtos (- ptascii_y 4.5)))

Specify base point: *Cancel*
bad argument type: numberp: "531632.7"

Your trying to subtract from a number that you already converted to a string:

(setq base_point (getpoint "\nSpecify base point: "))
(setq ptascii_x (car base_point))
(setq ptascii_x (rtos ptascii_x 2 2))
(setq ptascii_y (cadr base_point))
(setq point_calc (rtos (- ptascii_y 4.5)))

Whats wrong with the subject line of your post?

[alanjt]

thanks ronjonp i knew it was something silly. Se7en, is that a better subject line, sorry about being ambiguous?

[daron]

Would "why can't I subtract a real from a string" be a better subject line, 7?

[JohnK]

I dunno...To be honest, I never read the post (Nothing personal, I saw a response and assumed it was taken care of).

A good subject line is for your benefit not mine (well it is in a obscure way.). You get better help if people know what the question is before they read the actual question.

A: Se7en cannot understand it as it relates to the subject matter presented by the question.

Q: Do I win the prize?
Q: Is there a prize?

How should i know?! Did you answer correctly?
I didn't know there was a contest.

[daron]

What was the original name?

[alanjt]

I'll take that as a resounding NO on both accounts

[daron]

what's wrong with this code?

Hmm. I see nothing wrong with that title. I've seen worse. At least that let's us know that you have tried something and it's not quite working.

i'm not trying to make an enemy here, but seriously Se7en?

[JohnK]

Not `trying'? Your not `trying' by posting a private message in a public forum?

But to answer your question; whats wrong with me trying to explain where im coming from so you dont take what i say the wrong way (get angry)?

What you just did (post a PM in public) is NOT cool, not cool by any means. If you had a problem with what i PM'ed you, you should have either reported me to a moderator or just wrote me back saying that you didnt not want to speak with me.

Am i angry? Yeah kinda.
*Was* i angry? Not at all.
Was i trying to make you angry? Never!
Did you make an enemy? Not with me.
(but we will see how other people react to you posting PMs.)

John, since you chastised Alan publically perhaps your link and reasoning may have been better posted as well .. takes the same energy and everyone benefits.
