Formatting a number with exactly two decimals in JavaScript

Question

I have this line of code which rounds my numbers to two decimal places. But I get numbers like this: 10.8, 2.4, etc. These are not my idea of two decimal places so how I can

Answer 1

toFixed(n) provides n length after the decimal point; toPrecision(x) provides x total length.

Use this method below

// Example: toPrecision(4) when the number has 7 digits (3 before, 4 after)
    // It will round to the tenths place
    num = 500.2349;
    result = num.toPrecision(4); // result will equal 500.2

AND if you want the number to be fixed use

result = num.toFixed(2);
