Question

我正在使用HTML + CSS + AngularJS制作一个简单的计算器。一切都很好，但我想添加一个SquareRoot功能。这是一些代码：

 function _solve(){
switch(_state) {
  case 'ADD':
    _total +=  parseFloat($scope.console);
    $scope.console = 0;
    break; //similar for the rest of the operations

$scope.add = function() {
    _solve();
_state = 'ADD';} //this is how i call the function.

这是我对Sqrt的想法，但我认为不好：

$scope.getSqrt = function() {
$scope.console = (parseFloat($scope.console) * Math.Sqrt).toString();}

Answer 1

Math.sqrt是一个函数，这意味着您需要将要应用函数的数字放在括号内，如此

NM_CUSTOMDRAW

Answer 2

您需要将您希望从平方根中提取的数字作为参数提供给__author__ = 'Janis' # -*- coding: utf-8 -*- #!/usr/bin/env python import tweepy impot time # Initialize tweepy functions------------------------------------------------ CONSUMER_KEY ='' CONSUMER_SECRET = '' ACCESS_TOKEN = '' ACCESS_TOKEN_SECRET = '' auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET) api = tweepy.API(auth) class Listener(tweepy.StreamListener): def on_status(self, status): print status.text return True def on_error(self, status_code): print 'Error in streaming' print status_code pass keyword = 'ISIL' twitterStream =tweepy.Stream(auth=auth, listener=Listener()) twitterStream.filter(track=[u'الإسلامية'])函数，例如：

Math.sqrt()
