I have following table and JavaScript that calculates my temperature to farenheid.
I want to toggle between celcius and Fahrenheit but obviesly if i reverse the calculation after I round the number the temperature is different.
I would like the original number back. I have About 200 different numbers all with the same class. I hope somone could help me. Thank you.
function change_to_gf()
{
var myClasses = document.getElementsByClassName("a_e");
for (var i = 0; i < myClasses.length; i++)
{
myClasses[i].innerHTML = (((myClasses[i].innerHTML -32 ) / 1.8) | 0)
}
var myClasses = document.getElementsByClassName("a_mr");
for (var i = 0; i < myClasses.length; i++)
{
myClasses[i].innerHTML = (((myClasses[i].innerHTML -32 ) / 1.8 | 0))
}
}
<table style="width:920px;" align="center" id="sort1" data-name="mytable" class="4sort1">
<tr>
<td style="width:60px;" class="a_e" id="exo_bist_e"/>48
<td style="width:60px;" class="a_mr" id="exo_bist_mr"/>52
