BigInteger in JavaScript mode

ch3

Has anyone used it successfully in processing.js? I get [ReferenceError: BigInteger is not defined]

import java.math.BigInteger;


void setup ()
{
  size( 800, 600 );
  colorMode(RGB,1);
  background(0);

  text("Hello World!", 50, 50);
  BigInteger b = new BigInteger("183972267825065276461950095037660073391");
  text(b.toString(), 50, 100);

}

Only a tiny fraction of Java's API is available for PJS:
http://ProcessingJS.org/reference/

You'll have to find an equivalent JS library for it, I'm afraid...

oh I see.

So in this post, someone lists a few of them. http://stackoverflow.com/questions/14531137/what-javascript-library-can-i-use-to-manipulate-big-integers

Is it a matter of downloading one of them and importing it in my sketch? How exactly do I do this?

thank you

• AFAIK, just paste the ".js" along w/ your ".pde" in "JavaScript Mode".
• Then you can instantiate the new class from that file inside ".pde".
• Notice you're gonna lose cross-mode compatibility w/ "Java Mode".
• Unless that JS' API matches that of Java's...

I also tried to import de.bezier.guido.*; from the 'Import library' menu and it fails as well.

Is it for the same reason? Can I not import any other libraries and limit my self to the functionalities of the core functions listed in the reference you pointed out?

Ah ok, let me try your suggestion above.

thank you for helping

ok great! I managed to make bigInteger to work. I see the syntax is somewhat different, as well as non jave compatible as you mentioned.

I will now look for a gui library as well.

thank you so much!
