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;
}

i am working on a Web3 project where i have a balance of tokens which i want to burn. The problem that the amount of balance is in this format
0.29806008728157019
So when i pass this amount to the burn method it loss its precision and it becomes
0.2980600872815702
I've tried many things like converting it to big number before passing it as a parameter like this
web3.utils.toBN( Math.trunc(amount * 1000000000000000000) );
i tried to convert it to a string then use parseFloat like this:
const value = web3.utils.toBN(
Math.trunc(parseFloat(amount) * 1000000000000000000)
);
But none of these worked.
Any help please ?

I tried to format the Amount field to 2 digits using the
Amount.toLocaleString()
toLocaleString(undefined, { minimumFractionDigits: 2 }),
Some of the Amount values are displayed correctly but few are incorrect
like $52.85.00 should be displayed as $52.85
function financial(x) {
return Number.parseFloat(x).toFixed(2);
}
console.log(financial(123.456));
console.log(financial(0.004));`
You can use Number.prototype.toFixed() to format with a number of decimals. Note: The toFixed method will return a string, so you should convert back to an floating number if your goal is not just to display. For more info on .toFixed() method access document
let numberToBeFormatted = 212.121212;
let formattedNumber = parseFloat(numberToBeFormatted.toFixed(2))

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

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);
