C is more straight forward: typecasts don't look like a function so you are not astonished to see that they don't perform any action. abs() does not exist in C (you can of course do a simple #define macro for that). -Michael -- Rapidly troubleshoot problems before they affect your business.

Re: [MSEide-MSEgui-talk] MSElang, implicit type conversions
Yes.. of course ;) almost everything is in a library.. but it's standard library. Abs in pascal is also in a library (System unit) is not part of the language.. like almost every thing. I'm not sure but probably stdlib.h is in every C implementation out there. 2013/12/18 Michael Schnell mschn...@lumino.de On 12/18/2013 10:26 AM, Julio Jiménez wrote: Not true.

Re: [MSEide-MSEgui-talk] MSElang, implicit type conversions
Really ? I had the impression that it is a compiler builtin. Probably I'm wrong in the concept. Compiled by default doesn't mean is part of the language IMHO, you also can apply the same to abs in C language stdlib.h curious.. you can read http://www.freepascal.org/docs-html/rtl/system/ ...The system unit contains the standard supported functions of Free Pascal. It is the same for all platforms. Basically it is the same as the system unit provided with Borland or Turbo Pascal standard.. like standard lib in C I was only responding to your sentence: abs() does not exist in C (you can of course do a simple #define macro for that). You don't need to define abs in C, just use stdlib.h, this is what I wanted to say.. :) -- Julio Jiménez Borreguero -- Rapidly troubleshoot problems before they affect your business.
