Hello, Cos of 90º (degress) is 0.

But If I code this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i C := Cos
(gradtorad (90)); 
C isn't 0, it's 0.1564....

My Lazarus is 0.9.30 "Oficial" Release.

it's a bug?, Did I samething wrong?

I think you need to use DegToRad in stead of GradToRad
