function createfields() {     $('.field').remove();     var container = $('#container');     for(var = 0; < +$('input:text').val()+1; i++) {         $('<div/>', {             'class': 'field',             'text':          }).appendto(container);     } }  function distributefields() {       var fields = $('.field'), container = $('#container'),         width = center.width()*2, height = center.height()*2,         angle = 0, step = (2*math.pi) / fields.length;     var radius = width/2;     var containerlength=$('input:text').val();     angle=step* (containerlength-1);      fields.each(function() {          var x = math.round(width + radius * math.cos(angle));         var y = math.round(height + radius * math.sin(angle));             $(this).css({             right: x + 'px',             top: y + 'px'         });         angle -= step;      }); }  var center = $('#center');  $(window).resize(function(height) {      $('#container').width($(window).height()*0.9)     $('#container').height($(window).height()*0.9)     var width = $('#container').width() * 0.4;      console.log("width",$('#container').width());     console.log("height",$('#container').height());     var radius = width/2;     width += 'px';     radius += 'px';     center.css({         width: width, height: width,         '-moz-border-radius' : radius,         '-webkit-border-radius' : radius,         'border-radius' : radius     });  createfields(); distributefields();     // rest of code font-size setting etc.. });  $(window).resize();   $('input').change(function() {     createfields();     distributefields(); });

your initial angle must changed.

angle = -90*math.pi/180; // (deg) * [math.pi/180 == rad deg] //we have provide values in radians, convert our degrees radians
