Description

return ordinal value of a number

Setup

function ordinal (a){return["th","st","nd","rd"][(a=~~(a<0?-a:a)%100)>10&&a<14||(a%=10)>3?0:a]}
    
    function ordinal2(a){return a=a%10,["th","st","nd","rd"][(a=~~(a<0?-a:a)%100)>10&&a<14||(a%=10)>3?0:a]}
    
    function ordinalWithRegExp (a){return[,"st","nd","rd"][/1?.$/.exec(a)]||"th"}
