What I’m looking to do with the following form is when a user inputs a certain length width and depth the output will be set to a certain number of characters. Basically looking to add a zero before an input of a number lower than 10 in two fields (product_number & product_id)
For example if a user inputs:
Length: 20.25 Width: 5.625 Depth: 9.125
the output I would like to have would be:
product_number: RSC_20.25_05.63_09.13
product_id: 1203056091
Right now the output looks like this:
product_number: RSC_20.25_5.63_9.13
product_id: 12035691
The reason for this is so when I sort my products in my shop they will go in the correct numerical order as well as making everything easier to maintain. I only need it to be 2 digits before the decimal point because the max number input will never be over 99…
Here is the code:

<script>
Number.prototype.eighths= function(prec, ret){
prec= prec || 8;
while(prec%4)++prec;
var i= Math.floor(this),
s= i? i +’-‘:”,
num= this-i, div= 1/prec, mod= prec/4,
mag= Math.pow(10, Math.log(prec*2)/Math.log(2)),
f1= Math.round(mag*(num/div))/mag,
f= Math.round(f1);
if(f1-f> div/4) f= Math.ceil(f1);
if(f== 0) return i;
if(f== prec) return i+1;
if(ret=== 1) return s+f+’/’+prec;
if(f*2== prec) return s+’1/2’;
while(mod>= 2){
if(f%mod=== 0) return s+ f/mod+’/’+prec/mod;
mod/= 2;
}
return s+f+’/’+prec;
}
function calculate(){
var F=document.frmRSC,
l= Number(F.txtlength.value);
w= Number(F.txtwidth.value);
d= Number(F.txtdepth.value);
Q = Number(F.txtqty.value) /* Quantity */
Lrounded = (Math.ceil(l/.125)/8)
Wrounded = (Math.ceil(w/.125)/8)
Drounded = (Math.ceil(d/.125)/8)
F.product_number.value= ‘RSC_’+Lrounded.toFixed(2)+’_’+Wrounded.toFixed(2)+’_’+Drounded.toFixed(2);
F.product_id.value= ‘1’ + (Lrounded.toFixed(1)*10) + ” + Wrounded.toFixed(1)*10 + ” + Drounded.toFixed(1)*10
}
