Example of digital formatting usage for Android implementation _android

The examples in this article describe the digital formatting usage that Android implements. Share to everyone for your reference, specific as follows:

Package formatnumber;
Import Java.text.DecimalFormat;  public class FormatNumber {public static void main (string[] args) {DecimalFormat df = new DecimalFormat (); Double data =
1234.56789;
System.out.println ("Pre-formatted number:" + data);  String style = "0.0";//defines the format of the number to display Df.applypattern (style);//applies formatting to the formatter System.out.println (after formatting with style: + style +): "
+ df.format (data));
style = "00000.000 kg";//Add characters such as units Df.applypattern (style) after formatting;
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data));
The "#" in the pattern indicates that if the bit exists, the character is displayed and is not displayed if it does not exist.
style = "# #000 kg";
Df.applypattern (style);
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data));
The "-" in the pattern indicates that the output is negative and should be placed at the front style = "-000.000";
Df.applypattern (style);
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data));
In the pattern, "," adds a comma to the number to facilitate reading the number style = " -0,000.0#";
Df.applypattern (style);
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data)); "E" in the pattern indicates that the output is exponential, the string before "E" is the base format,///"E" after the string is the exponential latticeStyle style = "0.00E000";
Df.applypattern (style);
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data));
The "%" in the pattern is multiplied by 100 and displayed as a percentage, to be placed at the end.
style = "0%";
Df.applypattern (style);
SYSTEM.OUT.PRINTLN ("Use style:" + style + "after formatting:" + df.format (data)); The "\u2030" in the pattern is multiplied by 1000 and displayed as a thousand score, to be placed at the end.
style = "0.00\u2030"; Set the number format in the constructor DecimalFormat df1 = new DecimalFormat (style);
Df.applypattern (style);

 SYSTEM.OUT.PRINTLN ("Use style: + Style +" after formatting: "+ df1.format (data));}

The result of the program running is:

Number before formatting: 1234.56789
after style:0.0 format: 1234.6
with style:00000.000 kg format: 01234.568 kg
uses style: # #000 000 After kg format: 1234.568 kg is formatted
with style:-000.000: -1234.568
adopts style: -0,000.0# after formatting: -1,234.57
adopts style: 0.00E000 after the format: 1.23E003 after the
adoption of style:0.00% format: 123456.79%
adopted style:0.00‰ format: 1,234,567,.89
