Interesting topic.

I learned all about Double.POSITIVE_INFINITY!

https://stackoverflow.com/ has some good discussions about:
Double.POSITIVE_INFINITY

It is important to know the sizes of data types.

References for the sizes of primitive data types:

An exercise I worked through:

println(2147483647);
println(2147483647+1); //Take a good look at the integer output for this!
//println(2147483648); See the warning for this! 
//Warning in console:
//The type *int* can't handle numbers that big. Try 2147483648L to upgrade to long.
println(2147483648L);
println();

int xInt = 2147483647;
println(xInt);
println(xInt+1);
println();

long xLong1 = 2147483647 + 1;
//println(xLong1);
System.out.println(xLong1);
println();

long xLong2 = 2147483647L + 1L;
//println(xLong2);
System.out.println(xLong2);
println();

for(int i = 2147483647-3; i>0; i++)
  {
  println(i);
  }
println();
  
for(int i = 2147483647-3; i<214748368L; i++)
  {
  println(i);
  }
println();     
  
for(int i = 2147483647-3; i<2147483647; i++)
  {
  println(i);
  }
println();   
  
//An infinite loop - uncomment this if you want to run it:
//for(int i = 2147483647-3; i<=2147483647; i++)
//  {
//  println(i);
//  }
//println();      
    
// An infinite loop - uncomment this if you want to run it:
//for(int i = 2147483647-10; i<2147483648L; i++)
//  println(i);

why is this not working?

int x=19999;
int i=0;

void draw(){

if (i==0){
  print(0.);}
  
for( i=0; i<x; i++){ 
  
     if (i==x){
       print(1);
       stop();}}}

Just for fun, but not for the sake of efficiency, can you do it without a for or while loop?

Try this, and think about how it works:

void setup() {
  print_char_x_times('a', 20);
}

void print_char_x_times(char ch, int times) {
  if (times > 0) {
    print(ch);
    // recursive function call
    print_char_x_times(ch, times - 1);
  }
}

Please use ctrl-t in processing prior to posting

It doesn’t work because for loop stops 1 before x and x is never reached

Hello,

It is good to develop the skills to seek out resources and examine your own code.

Example:

int x=19999;
int i=0;

void setup()
  {
  println("a", i, x);
  for(i=19990; i<x; i++)
    { 
    println("b", i, x);  
    if (i==x)
      {
      print("c", i);
      }
    }
  }
