Add a Zero (0) in front of numbers below ten (10)

In certain situation I need to add a zero in front of numbers below ten. It could be used for money, .05 and for time :05 and I’m sure there are other situations where this could be useful.

// add zer0 in front of minutes below ten 10
function pad(n) {if (n < 10) return “0” + n; return n;}

// use the pad function
for(var minute=0; minute<50;minute=minute+5){
$(“#minutes”).append(“<option value='”+pad(minute)+”‘>”+pad(minute)+”</option>”);
}
