Closed 3 years ago.
I am trying to display some decimal points.
Here are some examples.
console.log(1/100); // 0.01;
console.log(1/1000000); // 0.000001;
console.log(1/10000000); // le-7; but I want to see 0.0000001;
console.log(1/100000000); // le-8; but I want to see 0.00000001;
How to show decimal point numbers with keeping format?

You can use .toFixed(n):
console.log((1/10000000).toFixed(10))

I take data from Spreadsheet, So I use the below formula in App script
Now the data in spreadsheet value=2.33344443333
Hence in HTML same 2.33344443333 it's showing when i call emailTemp.data, Please help me to change to have only 2 decimal value like 2.33
Appscript:
data.forEach(function(row){
emailTemp.data=row[value];
}
.toFixed(2) would round a decimal value to two spaces as a string. Presumably the following would work if you didn't need to access the value as a decimal later on:
data.forEach(function(row){
emailTemp.data=row[value].toFixed(2);
}
Try this :
data.forEach(function(row){
emailTemp.data = Math.round(Number(row[value]) * 100) / 100;
}

This code outputs a number with many decimal places.. I'd like it limited to just one... this code gets me my desired result BUT with too many characters displayed.
I'm a total noob....
function oninputchange() {
$output.textContent = $input.value.split(/\s/g).map(syllable).reduce(sum)/4.7;
}
The results are expected... Just want fewer decimal places
Use method toFixed() for limit the decimal number to show

How to get the first four decimal numbers in Javascript using math.ceil? [duplicate]

How to round up a number in Javascript?

Currently have the following javascript code:
div.html( Drupal.t("Date")+": "+d.date+"</br>"+Drupal.t("Value")+": " + (d.value))
Value that i'm getting is 0.1651859999999985 . I wanna round it off to the first four decimal numbers. Any help? I tried Math.ceil(d.value*10)/10) but it was only getting the first decimal :( Any help? I wanna get 0.1652
Should be Math.ceil(d.value*10000)/10000
example:
console.log(Math.ceil(0.1683123*10000)/10000)
console.log(Math.ceil(823.124148336763*10000)/10000) // round up to the ceiling
console.log(Math.floor(823.124148336763*10000)/10000) // round down to the floor
console.log(Math.round(823.124148336763*10000)/10000) // below .5 -> down, above .5 -> up

I'm adding 0.5 to a number every second. However, it seems to be adding 0.5000000000001 instead.
window.setInterval(function() {
number += 0.5;
// it says number as 0.50000000001, and after 1.00000000002
}, 1000);
Does anybody know why this is happening?
It is a limitation of floating point numbers. They are not that accurate and hence the values that you have obtained.

How can I make a flaoting point number always have two decimal places, even when one is a zero?
E.g var postageCost = 3.2 but I want to display it as 3.20 - is this something that must be added as a string or is it possible to actually change the number?
From Here, you can use
parseFloat(Math.round(postageCost * 100) / 100).toFixed(2);
