I have numbers in table and need to format them with JavaScript (2 symbols after dot). This code works but I guess there are more efficient and elegant ways:
var str = "126389471.74000001";
var dotIndex = str.indexOf(".");
var formattedStr = str.substring(0, dotIndex+3);
Could anybody suggest better solution?
You're looking for toFixed
var str = "126389471.74000001";
var formattedStr = parseFloat(str).toFixed(2); // 2 dp
Why do you treat them as strings in the first place? It would be much better to use JavaScript to automatically handle this with toFixed():
var num = 126389471.74000001,
formatted = num.toFixed(2);
If you absolutely have to treate it as a string, use parseFloat() and the same method:
var formatted = parseFloat(num).toFixed(2);
