Title: Getting extra charcters when using RTOS
Post by: Krushert on April 12, 2011, 04:04:29 PM

So I started with some of Kerry's code (http://www.theswamp.org/index.php?topic=10317.msg131450#msg131450) and then realizing it is spitting out in real numbers and I need to convert to string form.  When I tried to do it I am getting extra characters.  Why???  If I remove the rtos, it retuns the real number in the correct form.

Quote

"3'-3 1/4\" "
_$

it should read 3'-3 1/4"

Code: [Select]

(SETQ DimEnt2  (CAR (ENTSEL "\nSelect Height Dimension :") )
         DimObj2  (VLAX-ENAME->VLA-OBJECT DimEnt2)
         Measurement2 (rtos (VLAX-GET DimObj2 'Measurement) 4 6)
)

Try the two  :-) :

(alert "3'-3 1/4\"")

(alert "3'-3 1/4")

Okay?  :|   That is weird.

But I can see that I did not take it far enough.  I was just looking at what was being returned in watch window thinking that was what I was going to get.

Thank you.

Ask yourself: How does one express a quotation mark in a string without signifying the end of the string itself?

The same applies to the backslash - consider the following:

Code: [Select]

(alert "a\tb")

Code: [Select]

(alert "a\\tb")

Or try (alert (chr 34))  :lol:
