JavaScript四舍五入并保留两位小数

在JavaScript中，有一个问题一直被没有很好地解决，就是小数点保留指定的位数，也就是我们通常说的Math.Round()函数。

首先，JavaScript有自带的Math.Round()函数，能够对一个浮点数进行四舍五入，但是返回的结果是个整数，无法精确到小数点后。

Number.toFixed()方法，能保留小数点后面的指定位数，但如果执行2.1.toFixed(2)的话，会返回2.10，而不是我们期待的2.1，所以，这个方法也不太可取。

最近我发现一个很简单的方法，假设我要对0.105进行四舍五入并保留两位小数，如果直接调用Math.Round()的话，结果是0，如果直接调用.toFixed(2)方法的话，会返回0.10，最简单有效的方法就是对0.105先乘以100，再调用Math.Round()，然后再除以100，就OK了。 

var number = 0.105;
alert(Math.round(number * 100) / 100);

网页弹出0.11

举一反三，如果你想保留三位小数，就是

Math.round(number * 1000) / 1000

如果你想转换为百分比，再保留两位小数，就是

(Math.round(number * 10000) / 100) + '%'

PHP - FREE CODE ENCRYPTION | ALTERNATIVE OF ZEND | EASY| ENCODING | PROTECTED PHP CODE | TUTORIAL

 

 

Yes, you can definitely hide/encode/encrypt the php source code and 'others' can install it on their machine. You could use the below tools to achieve the same.

• Zend Guard
• IonCube
• SourceGuardian
• phpSHIELD
• phpBolt (free)

But these 'others' can also decode/decrypt the source code using other tools and services found online. So you cannot 100% protect your code, what you can do is, make it tougher for someone to reverse engineer your code.

Most of these tools above support Encoding and Obfuscating.

• Encoding will hide your code by encrypting it.
• Obfuscating will make your code difficult to understand.

You can choose to use both (Encoding and Obfuscating) or either one, depending on your needs.

This is a...passing thought, though I'm not sure how practical it would be:

<span class="protectedNumber" title="01234567890"></span>

css:

span.protectedNumber:before {

How To Use The scp Command to Copy a File From Remote to Loca

 

You uploaded a debuggable APK. For security reasons you need to disable debugging before it can be published in Google Play-Upload apk to google play

Don't use the debug variant output! Build a release apk. You can do that in Android Studio by going to the menu Build -> Generate Signed APK. Or by executing ./gradlew assembleRelease if you have properly configured signing in the build file.

Delphi XE5 获取Android手机网络状态

 https://blog.csdn.net/weixin_30607659/article/details/95270618

介绍

本文章介绍了Delphi XE5 获取Android手机网络状态，通过该代码可以得到Wift是否连接、手机网络是否连接，首先会实现一个类库Androidapi.JNI.Network，然后通过这类库来判断网络状况。

在使用这个类库之前，需要配置手机的权限，否则无法得到信息。

下面是这个判断类库的代码：

unit Androidapi.JNI.Network;

interface

function IsConnected: Boolean;

function IsWiFiConnected: Boolean;

function IsMobileConnected: Boolean;

implementation

uses
System.SysUtils,
Androidapi.JNIBridge,
Androidapi.JNI.GraphicsContentViewText,
Androidapi.JNI.JavaTypes,
FMX.Helpers.Android;

type
JConnectivityManager = interface;
JNetworkInfo = interface;

JNetworkInfoClass = interface(JObjectClass)
['{E92E86E8-0BDE-4D5F-B44E-3148BD63A14C}']
end;

[JavaSignature('android/net/NetworkInfo')]
JNetworkInfo = interface(JObject)
['{6DF61A40-8D17-4E51-8EF2-32CDC81AC372}']
{Methods}
function isAvailable: Boolean; cdecl;
function isConnected: Boolean; cdecl;
function isConnectedOrConnecting: Boolean; cdecl;
end;
TJNetworkInfo = class(TJavaGenericImport<JNetworkInfoClass, JNetworkInfo>) end;

JConnectivityManagerClass = interface(JObjectClass)
['{E03A261F-59A4-4236-8CDF-0068FC6C5FA1}']
{Property methods}
function _GetTYPE_WIFI: Integer; cdecl;
function _GetTYPE_WIMAX: Integer; cdecl;
function _GetTYPE_MOBILE: Integer; cdecl;
{Properties}
property TYPE_WIFI: Integer read _GetTYPE_WIFI;
property TYPE_WIMAX: Integer read _GetTYPE_WIMAX;
property TYPE_MOBILE: Integer read _GetTYPE_MOBILE;
end;

[JavaSignature('android/net/ConnectivityManager')]
JConnectivityManager = interface(JObject)
['{1C4C1873-65AE-4722-8EEF-36BBF423C9C5}']
{Methods}
function getActiveNetworkInfo: JNetworkInfo; cdecl;
function getNetworkInfo(networkType: Integer): JNetworkInfo; cdecl;
end;
TJConnectivityManager = class(TJavaGenericImport<JConnectivityManagerClass, JConnectivityManager>) end;

function GetConnectivityManager: JConnectivityManager;
var
ConnectivityServiceNative: JObject;
begin
ConnectivityServiceNative := SharedActivityContext.getSystemService(TJContext.JavaClass.CONNECTIVITY_SERVICE);
if not Assigned(ConnectivityServiceNative) then
raise Exception.Create('Could not locate Connectivity Service');
Result := TJConnectivityManager.Wrap(
(ConnectivityServiceNative as ILocalObject).GetObjectID);
if not Assigned(Result) then
raise Exception.Create('Could not access Connectivity Manager');
end;

function IsConnected: Boolean;
var
ConnectivityManager: JConnectivityManager;
ActiveNetwork: JNetworkInfo;
begin
ConnectivityManager := GetConnectivityManager;
ActiveNetwork := ConnectivityManager.getActiveNetworkInfo;
Result := Assigned(ActiveNetwork) and ActiveNetwork.isConnected;
end;

function IsWiFiConnected: Boolean;
var
ConnectivityManager: JConnectivityManager;
WiFiNetwork: JNetworkInfo;
begin
ConnectivityManager := GetConnectivityManager;
WiFiNetwork := ConnectivityManager.getNetworkInfo(TJConnectivityManager.JavaClass.TYPE_WIFI);
Result := WiFiNetwork.isConnected;
end;

function IsMobileConnected: Boolean;
var
ConnectivityManager: JConnectivityManager;
MobileNetwork: JNetworkInfo;
begin
ConnectivityManager := GetConnectivityManager;
MobileNetwork := ConnectivityManager.getNetworkInfo(TJConnectivityManager.JavaClass.TYPE_MOBILE);
Result := MobileNetwork.isConnected;
end;

end.

 

通过这个类库，我们可以调用IsConnected、IsWiFiConnected、IsMobileConnected函数来判断网络状况

function GetNetworkState: string; // 得到当前网络连接状态
var
　NS: TNetworkState;
begin
　NS := TNetworkState.Create;
　try
　　if not NS.IsConnected then // 无网络
　　　result := '0'
　　else if NS.IsWifiConnected then // wifi
　　　result := '1'
　　else if NS.IsMobileConnected then // 移动数据
　　　result := '2';
　finally
　　　NS.Free;
　end;
end;
