  3.6 or 3,6? Comma or dot sign?

  //Expression 1
  -Math.cos(time*3,6)*50+50;
  //Expression 2
  -Math.cos(time*3.6)*50+50;

  Hi!

  I was writing an expression and noticed that there is a difference in notation of decimal numbers between the American style – dot (.) – and the European style – comma (,).

  What is the difference? Which should I use?

  For example:
  When I use a comma in the expression, I get this post-expression graph (Expression 1):
  
  However, when I use a dot in the expression, I get the following (Expression 2):
  

  Just one of my many sigs:
  The American people have always had problems with the immigrants. Ask American Indians… XD

  It appears that Math.cos(time*3,6) just ignores the number after the comma, so you’re just getting the same result as you would with Math.cos(time*3). 3.6 gives you the correct result (at least for the version of AE that you’re running).
