Nodejs Utililty Methods String to Float Convert

Number.prototype.tryParseToFixed = function(decimalPlaces) {
  if(!decimalPlaces) decimalPlaces = 0;
  if (isNaN(this)) {
    throw this + ' could not be converted to a Number.';
  return parseFloat(this).toFixed(decimalPlaces);

String.prototype.toFloat = function() {
  return parseFloat(this);

String.prototype.toFloat = function(){

  var dy = ey - cy;
  var dx = ex - cx;
  var theta = Math.atan2(dy, dx); 
  theta *= 180 / Math.PI; 
  return theta;
