How to format numbers similar to Stack Overflow reputation format
UPDATE: CMS got the check and provides a superior answer. Send any more votes his way.
// formats a number similar to the way stack exchange sites
// format reputation. e.g.
// for numbers< 10000 the output is '9,999'
// for numbers > 10000 the output is '10k' with one decimal place when needed
function getRepString(rep)
{
var repString;
if (rep < 1000)
{
repString = rep;
}
else if (rep < 10000)
{
// removed my rube goldberg contraption and lifted
// CMS version of this segment
repString = rep.charAt(0) + ',' + rep.substring(1);
}
else
{
repString = (Math.round((rep / 1000) * 10) / 10) + "k"
}
return repString.toString();
}
Output:
getRepString(999)
== '999'getRepString(1000)
== '1,000'getRepString(9999)
== '9,999'getRepString(10000)
== '10k'getRepString(10100)
== '10.1k'
Another approach that produces exactly the desired output:
function getRepString (rep) {
rep = rep+''; // coerce to string
if (rep < 1000) {
return rep; // return the same number
}
if (rep < 10000) { // place a comma between
return rep.charAt(0) + ',' + rep.substring(1);
}
// divide and format
return (rep/1000).toFixed(rep % 1000 != 0)+'k';
}
