Print ".00" When The Result Is A Whole Number?

Question

I want to try and print ".00" after the variables cache.todayHigh and cache.todayLow are whole numbers.

if (ddimgtooltip.showTips) {
  // update tooltip
  tip = 'High ' + strings.baro_info + ': ' + cache.todayHigh + ' ' + data.pressunit + ' ' + strings.at + ' ' + data.TpressTH +
  ' <br> ' + strings.minimum_info + ' ' + strings.baro_info + ': ' + cache.todayLow + ' ' + data.pressunit + ' ' + strings.at + ' ' + data.TpressTL;

  if (cache.trendVal !== -9999) {
    tip +=  '<br>' + strings.baro_trend_info + ': ' + baroTrend(cache.trendVal, data.pressunit, true) + ' ' +
    (cache.trendValRnd > 0 ? '' : '') + cache.trendValRnd + ' ' + data.pressunit + '/hr';
  }

  $('#imgtip5_txt').html(tip);
}

e.g. 1017 hPa to 1017.00 hPa.

Is this possible?

Thanks,

William

Thanks, adeneo. I presume "numb" is where the cache.todayHigh/Low are inserted? — William Grimsley, Aug 06 '16 at 13:53

Thanks everyone, I'm struggling how I'm supposed to insert this into the code above? Is it as a seperate line, if statment or inside the original if statement? — William Grimsley, Aug 06 '16 at 14:16
Yes, potentially, though the value changes as this is part of my weather website, it's not one specific value. So, would I replace '1702 hPa' with something else? — William Grimsley, Aug 06 '16 at 14:25
@WilliamGrimsley now its hardcoded , you can dynamically change it with your own value — rejo, Aug 06 '16 at 14:42
But, I don't change the value, the value comes from the weather station itself. — William Grimsley, Aug 06 '16 at 14:55
http://www.newton-poppleford-weather.co.uk/gauges.htm, hover over the pressure gauge and see the low pressure value is shown as a whole number. — William Grimsley, Aug 06 '16 at 15:23

Try this,

var yvalue = '1702 hpa';
var num = yvalue.replace(/[^0-9]+/ig,"");
value = Number(num).toFixed(2);
var fvalue=  value +' '+yvalue.split(' ')[1]
console.log(fvalue);
