I've got the compiling error with the following codes:
Code:

---

// main.c
#include <acknex.h>
#include <default.c>

var aa;
var bb;
var cc;

void main()
{
   level_load("");
   bb = 10;
   cc = 20;
   aa = max(bb,cc);
}

---

Compiling MAIN.c........
Error in 'MAIN' line 14 : 'max' undeclared identifier
<aa = max(bb,cc);>

Can't compile MAIN.c
Startup failure - any key to abort

Same with aa = min(bb,cc);

max() is a standard C macro and can't be used for an engine function under lite-C. Use maxv() instead.

Ok, thanks.

Is this documented in the manual meanwhile?
I had the same problem recently and couldn't find it in the manual... I tried until I found the right call

uh not yet I think, cos I can't found any info
about maxv and minv from the manual, even the
migration page too!

there seems to be a similar problem with frc() and int(). These display the same error message.
Do frcv() and intv() exist?

yes, you can see these functions in afuncs.h
EDIT: sorry, int() changed to integer(), and frc() changed to fraction(). Anyway most changed to sinv, cosv and so on
