<script type="text/javascript">        
     
document.write("Math.Atan(1.0) = " + Math.atan(1.0) + "<br />");
document.write("Math.Atan(-1.0) = " + Math.atan(-1.0) + "<br />");
document.write("Math.Atan(0.0) = " + Math.atan(0.0) + "<br />");
document.write("Math.Atan(-0.0) = " + Math.atan(-0.0) + "<br />");
document.write("Math.Atan(Infinity) = " + Math.atan(Infinity) + "<br />");

/*
run:
  
Math.Atan(1.0) = 0.7853981633974483
Math.Atan(-1.0) = -0.7853981633974483
Math.Atan(0.0) = 0
Math.Atan(-0.0) = 0
Math.Atan(Infinity) = 1.5707963267948966
