JavaScript displaying a float to 2 decimal places
(14 answers)
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 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

Is floating point math broken?

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);
