will it once be possible to initialize arrays like

  int array[];
  array={0,3,5,2,9};

?

Removed some completely off-topic posts. Please keep this thread uncluttered. There's no lack of other threads that are more suited for banter

ok,
so when will the next NXC version be released?

What about a mod function?
It would return the remainder of the input float.
Like this:

Code: Select all

task main()
{
 int remainder;
  remainder=mod(5.7);
  //remainder should be 0.7
}

Also would it be possible to fill a polygon when creating a 3d shape?
The default would be transparent, because you can see lines behind lines.
The filled would be like this:

Code: Select all

glBeginObject();
glBegin(GL_FILL_POLYGON_WHITE);
glAddVertex(50,45,50);
//other vertexes....
glEnd();
glBegin(GL_FILL_POLYGON_BLACK);
glAddVertex(20,35,10);
//other vertexes....
glEnd();
glEndObject();

What about a mod function?
It would return the remainder of the input float.

I guess what you mean is a frac function, not modulo.
Modulo is the integer division remainder, (C function symbol: "%")
what you mean are the numbers behind the decimal point.

In ANSI-C I don't know a frac function (CMIIW), but you can build it by

Code: Select all

inline float frac(float myVal){
  return(myVal-(int)myVal); // (int) = explicite conversion - I'd wish to have it in NXC!!!
}

in NXC you may write

Code: Select all

inline float frac(float myVal){
  int ibuf=myVal;  // implicite conversion
  return(myVal-ibuf);
}

}

OR:

Code: Select all

/*
inline long trunc(float x)
{
    return(x);
}
*/

inline float frac(float x)
{
    return(x - trunc(x));
}

OR EVEN:

Code: Select all

Because, frac() is already defined in the NXC API.

oh *surprise* - didn't expect this.
NXCBSMTC...

could we possibly have a
"fast i2c mode" (i2c Highspeed Mode)
the way e.g. RobotC has got?
Some i2c devices then could be possibly driven at a higher i2c speed with faster i2c calls...!

Would it be possible to add a double?
for example:

Code: Select all

double x=78.5464325;

Adding support for a double type is not something I foresee ever happening. The existing firmware passes variables around as generic 4 byte types in a lot of places. Since a float is 4 bytes and you can store any of the smaller integer types within the 4 byte LONG used in the firmware then everything works okay. But if you tried to add support for a double which is greater than 4 bytes long then you would have to change all of that code. It would be a lot of work in the firmware and then I would have to do a lot of work in the compiler to handle a new type. Lots of work for not a whole lot of benefit.
