how can achieve this? can give sample code? thank can me this. i've tried code. whenever click radio button again value changing. think problem here structure of code. want know if .tofixed(2) solved 9999.99 format.. html

  <input type="radio" name="unitscale" id="opt1" onclick="changeunit()" checked class="roleauthorization"><label>metric (kg&cm)</label>   <input type="radio" name="unitscale" id="opt2" onclick="changeunit()" class="roleauthorization"><label>english (lbs&in)</label>

your question not clear.

but seems looking fix decimal points. if ,you can check , use tofixed method.

// rounding var x = 119.0484; document.write('<pre>'+x.tofixed(2)+'</pre>')   // without rounding var val = (math.floor(100 * x) / 100).tofixed(2); document.write('<pre>'+val+'</pre>')
