Topic: Tip (removing spaces from numbers)

[Mark]

Most of you probably know this but............

remove all spaces from around a number and return just the number

Code: [Select]

(rtos (atof "  34.988     ") 2 3)
--> "34.988"


same thing for integers

Code: [Select]

(itoa (atoi "  34     "))
--> "34"

Well, I'll be danged, I ain't gonna tell ya' how I have been doing it.

The other way could be to use find with a space and replace it with nothing, but Mark's way is much safer, until you can't convert it into a number like: "    34a   ".

The other way is to use VL ..

Code: [Select]


 (VL-STRING-TRIM " " "    34.988     " )
 (VL-STRING-TRIM " " "  34           " )
The poor cat gets skinned yet again ..

Nice Tip Mark!

To think I wrote a lisp that would eliminate spaces and convert a string number to a real number.  Its a good thing my lisp works with other string characters besides spaces or else I would feel real bad.
