int(random()); wierdness
« on: May 15th, 2003, 12:30pm » |

Hello, i've had a problem with this before, and i'm not sure what's wrong with it...
Code:int ytarget = int(random(h))-int(random(50));
|
|
Gives me this error...
Syntax error: found'('
I'm positive that there shouldn't be anything wrong with this. Is it something to do with the amount of ints i've liberally spread around?

not sure either, what's going on here... seems like a bug, but in anyway a more elegant (and working) version of this line would look like this:
int ytarget=int(random(h)-random(50));

try (int)'s instead of int()
eg
Code:int ytarget = (int)random(h)-(int)random(50);

Thanks guys. I had gotten round the problem, but I thought i'd post it and see whether there was some fundamental thing I was doing wrong.
Cheers.

the parser has problems with "int()" sometimes. we're currently working on replacing the current parser with something more reliable. the java native "(int)" will always work. i come across this problem often while coding with Processing. it's frustrating, i know.

int ytarget = (int)(random(h)-random(50));
should work just fine.  less typing of (int)'s

it may matter little, but just for the hell of further correctness:-
Code:| (int)(random(a)-random(b)); |
|
will statistically produce different results to
Code:| ((int)random(a)-(int)random(b)); |

there's a little diff there but you just want something random.
at any rate, it would matter in cases 3 + 4...
int a,b;
a = b = 50;
println( "1 \\ " + (int)(random(a)-random(b)));
println( "2 \\ " + ((int)random(a)-(int)random(b)));
println( "3 \\ " + (int)(3.142675-2.581158 ));
println( "4 \\ " + ((int)3.142675-(int)2.581158 ));

these sort of things will be fixed soon with a new parser that will be arriving from dan mosedale.

the parser has arrived and will be in rev 60. so these bugs are now fixed.
