abs() looks like a function but in fact it isn't. So it's a very special 
kind of function (at least it is similar to a set of overloaded 
function or a kind of generic).

In Pascal same is true for typecasts.

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).

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.

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

You don't need to define abs in C, just use stdlib.h, this is what I wanted
to say.. :)

One can always use explicit type conversions. MSElang principle is to make 
*no* implicit type conversions.
For abs() use

 integervar:= abs(integer(cardinalvalue));

Hallo Michael,

Sorry for stepping in, I promise I won't any more...

BUT: Does anybody _really_ think that type casting _does_ something?

A type cast, CPU wise, is a no-op, quite simply.
It is just a directive to the compiler that the programmer wants to do
something the language usually doesn't permit, i.e. interpret a variable of
one type as if it had another type. Often, this also includes size
conversion - but this is no real operation either, as this is done on the
fly by any common processor. Truncation simply means that part of the
value, i.e. part of a register's content, goes unused for the destination.
Expansion might even be disallowed altogether, or it might involve filling
the part missing in the source with zeroes. There's one special case,
though, that is when some compilers do sign extension on signed values,
which involves a processor instruction to the effect.

 abs() is a special beast, anyway...

What's so special about abs? Nothing at all. It's simply a comparison
used to decide whether to take the source value unchanged or negate it,
which usually is a single processor instruction. As pseudo code it would
look somewhat like:
IF value  0 THEN result:= -value ELSE result:= value;
Or in C:
result= value  0? -value: value;
Could be a preprocessor macro that way, even...

Correct, if the sizes of the types are the same a type conversion says to the 
compiler I know what I do.

For the conversion from smaller to bigger it either 
- sign extends the value if the conversion is signed to signed:

 int32var:= int32(int16value);

- it fills the upper bytes with 0 if the smaller or the bigger is unsigned:

 card32var:= card32(card16value);
 card32var:= card32(int16value); //possible range check?
 int32var:= int32(card16value);

If the conversion is from bigger to smaller it truncates to the lower bytes 
with a possible range check.

 card16var:= card16(card32value);
 card16var:= card16(int32value);
 int16var:= int16(card32value);
 int16var:= int16(int32value);

Even you don't :-) .

If you do unsigned := signed; you get the correct positive value if 
positive. But if it is negative you'll get maxunsigned + value + 1, as

This would be different to any known language and much slower.

 that's with side (unexpected/unwanted) effects.
 But what for to disable :

 unsigned := signed ?


var
 unsigned: card32;
 signed: int32;
...
 unsigned:= card32(signed);

Assigns the binary value as is, -1 - $.

 Here, user know what he/she wants to get (absolute value of the signed).


 unsigned:= card32(abs(signed));

Then 'Error: Icompatible types: got cardinal expected integer

fearing  misleadind than helping.

I think there should be no implicit type conversions in MSElang.
===
Maybe no UNSAFE (unsigned -2-signed etc with possible range/precision
loss,..) implicit type conversion ?

Yes.

var
 i1,i2: integer;
 c1: cardinal;
begin
 f1:= 1.0;            //ok
 f1:= float(1);       //ok
 i1:= 1;              //ok

Correction:

 c1: cardinal;
begin
 i1:= 1;  //ok
 c1:= 1;  //ok
 i2:= i1 + c1;//error

Or avoiding boring investigations: denying to assign unsigned to
signed because of possible value truncation - use explicit typecast if
