javascript - Round all decimals from dynamic JSON to 2 decimal places -


i making table pulling data dynamically json file , need able change value @ 2 decimal places. possible based on code have? examples of want do:

--7 changes 7.00

--3922.2 changes 3922.20

--89.2823 changes 89.28

thanks in advance!

here html:

<table id="reporttable" class="reporttable">     <th>timer name</th>     <th>daily percentile 90th</th>     <th>daily percentile 50th</th>       <th>min percentile 90th</th>     <th>max percentile 90th</th>     <th>daily average</th> </table>

here jquery , javascript:

//this code gets json, alphabetizes info, , populates table. var information = $.ajax({ type: "get", url: "http://websiteigetmyjsonfrom.com", datatype: "json", success: function (information) {     information.sort( function( a, b ) {         = a.timername.tolowercase();         b = b.timername.tolowercase();          return < b ? -1 : > b ? 1 : 0;     });      $.each(information, function(i, item) {         var $tr = $('<tr class="clickable">').append(             $('<td align="left">').text(item.timername),             $('<td>').text(item.daily_percentile_90th),             $('<td>').text(item.daily_percentile_50th),                          $('<td>').text(item.min_percentile_90th),             $('<td>').text(item.max_percentile_90th),             $('<td>').text(item.daily_average)).appendto('#reporttable');     }); }, error: function(){ alert("failed load json"); } });

example of json returned: 

{     "daily_percentile_90th": 4430.6,     "min_percentile_90th": 1598.8,     "max_percentile_90th": 5518.9,     "daily_percentile_50th": 3793.5,     "timername": "temple:shared",     "daily_average": 3745.16 }, {     "daily_percentile_90th": 1904.2,     "min_percentile_90th": 634.4,     "max_percentile_90th": 3296.6,     "daily_percentile_50th": 1103.5,     "timername": "search:catalog",     "daily_average": 1332.82 }, {     "daily_percentile_90th": 780,     "min_percentile_90th": 0.8,     "max_percentile_90th": 780,     "daily_percentile_50th": 239,     "timername": "ft:person:ordinances",     "daily_average": 397.324 },

use javascript numtofixed function:

var num = 5.56789; var n = num.tofixed(2);

the result of n be:

5.57

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
