Need help with Decoding Math watch

Hi,

I figured this would be a good place to get the answer to my question. I need help with decoding the 4 O'clock position of this geek watch (see attachment). It reads -[-pi] (???). If someone could tell me what is this referring to.

Thank you very much.

Well, slap my knee, but somehow -[-pi] = 4

Only way I can see this is [] means floor function

floor(-pi) = -4
-(-4) = 4

I rest my case...

Indeed. When you have mathematical typesetting it should be written but when you just have ASCII -[-pi] is fine.

By now I think everyone has realized that gives for positive x.
