The goal is to achieve two decimal places excluding zeros
1.2234 => 1.22
0.2345 => 0.23
0.02345 => 0.023 (instead of 0.02)
0.0000002345 => 0.00000023 (instead of 0)
0.0000002346545645645646465465 => 0.00000023 (instead of 0)
0.002035 => 0.002 instead of 0)
I am looking to format numbers using toFixed(2) but only on decimals that are not zero. What is the correct way to do this?
It appears that the intention is to dynamically remove the last two digits from a number rather than fixing it to two decimal places.
Here is my suggested approach to achieve this:
function eliminateLastDigits(number, amount = 2)
{
const numberString = number.toString();
if(numberString.indexOf('.') === -1) return number;
let numberLength = numberString.length;
for(; numberLength >= 0 && amount; numberLength--){
if (numberString[numberLength] !== '0') amount--;
}
return +numberString.slice(0, numberLength);
}
let inputNumber = 0.003040;
console.log(eliminateLastDigits(inputNumber)) //0.03
