round total...

[techker]

Hey guys i have tried a few combinations with no luck...

 

i have a tax cal for my invoice form but i need to round out the total not to have 1.23445

 

 

i have tried

 

 

 document.formname.Total.value = formname.Total.value.round (text1+text2+text3+text4+text5)* 0.14975 + (text1+text2+text3+text4+text5);

 

 document.formname.Total.value = Total.round (text1+text2+text3+text4+text5)* 0.14975 + (text1+text2+text3+text4+text5);

 

 

...

 

any clue how?

String does not have a method called round.

 

Use Math.round(document.formname.Total.value) instead.

[techker]

so i add it here?

 

document.formname.Total.value = (text1+text2+text3+text4+text5)* 0.14975 + (text1+text2+text3+text4+text5);

 

 Math.round(document.formname.Total.value)

[Irate]

Yeah, like that.

[techker]

doesnt work?

[Irate]

Alright, let's crack down this "problem".

 

What exactly are you trying to achieve?

[techker]

So i have an invoice and it calculates tax.works fine but i need to round the decimals.so i don't get 12.1234$

 

i have this

 

function calculate(){ 

 

 if(isNaN(document.formname.f1.value) || document.formname.f1.value==""){ 

 var text1 = 0; 

 }else{ 

 var text1 = parseInt(document.formname.f1.value); 

 } 

 

 if(isNaN(document.formname.f2.value) || document.formname.f2.value==""){ 

 var text2 = 0; 

 }else{ 

 var text2 = parseFloat(document.formname.f2.value); 

 } 

 

  if(isNaN(document.formname.f3.value) || document.formname.f3.value==""){ 

 var text3 = 0; 

 }else{ 

 var text3 = parseFloat(document.formname.f3.value); 

 } 

 

  if(isNaN(document.formname.f4.value) || document.formname.f4.value==""){ 

 var text4 = 0; 

 }else{ 

 var text4 = parseFloat(document.formname.f4.value); 

 } 

 

  if(isNaN(document.formname.f5.value) || document.formname.f5.value==""){ 

 var text5 = 0; 

 }else{ 

 var text5 = parseFloat(document.formname.f5.value); 

 } 

 

 

 

 document.formname.Total.value = (text1+text2+text3+text4+text5)* 0.14975 + (text1+text2+text3+text4+text5);

[Irate]

I see.

 

Try to do it like this, then.

 

function calculate() {

// your code here...

document.formname.Total.value = Math.round((text1+text2+text3+text4+text5)*0.14975+(text1+text2+text3+text4+text5));

That should do the trick.

[techker]

hey thx.

 

it works but it rounds up all the total..

 

i just need to remove the last decimals.

If you just want to truncate the number, use Math.floor(). That will just cut off the decimal without doing any rounding. Math.round does your traditional rounding based on what the decimal value is.
