[Javascript] Sorting Problem

[Tim Makins]

Well, that's a start. Its not crashing now, but the numerical search results
aren't quite right either:

0.129872
0.164749
0
10.1961
10.5643
1003
100
104.813049
10
11.390914
1121

function numeric_sort(a, b) {
 return (isNaN(a)&&isNaN(b))? alpha_sort(a,b): numSort(a,b);
}

function alpha_sort(a, b) {
 if (a < b) {return -1}
 else if (a > b) {return 1}
 else {return 0}
}

function numSort(a,b){
 return
(isNaN(a)?Number.POSITIVE_INFINITY:a)-(isNaN(b)?Number.POSITIVE_INFINITY:b)
}
