int() doesn't seem to work in the editor?

hanswillem

For me int() doesn't work. I get an error saying that int is not defined. I am using the p5 editor. Is this an editor issue?

Create a very simple example that demonstrates this error and post it here.

When I create a sketch with nothing more than this:

print(int("10"));

I get: Uncaught ReferenceError: int is not defined

Just deleted my last answer because I tested in Java mode.

I believe that p5.js is pure Javascript so I suspect that it is an invalid Javascript statement, but I leave that to someone who likes the language to answer it. ;)

But I have taken the int() command from the reference docs.

parseInt() seems to work though.

If you just wanna truncate an operation, simply adding up | 0 to it can be faster than parseInt(): :-B

• 11*1.5 | 0 results in 16 instead of 16.5
• 11/2 | 0 or 11>>1 results in 5 instead of 5.5

Nevertheless, parseInt() is still useful to safely convert other types like String to int! (*)

Including those w/ different radices like hexadecimal, octal, etc.! :P

Just to clarify. This is a link to the reference docs:

http://p5js.org/reference/#p5/int

But when I try it, I get an error saying: Uncaught ReferenceError: int is not defined

Guess you're gonna need to open an issue there: https://github.com/lmccart/p5.js/issues 8-|
