How to Format Floats with Specific Decimal Places in JavaScript?

Formatting Floats to Specific Decimal Places

In JavaScript, converting from a float to a string can result in trailing decimal digits. To limit the number of digits after the decimal point, you can employ specific functions.

Rounding Functions

One approach is to use rounding functions, such as toFixed. For instance:

<code class="javascript">var number = 0.3445434;
console.log(number.toFixed(2)); // Output: "0.34"</code>

By specifying 2 as the argument to toFixed, you limit the decimal places to two, resulting in the desired output of 0.34.

Edit: JSFiddle Demonstration

For a live demonstration, refer to the following JSFiddle:

In this example, a float variable is defined, and its value is formatted to two decimal places using the toFixed function. The output is displayed in the console, demonstrating the precision achieved by the function.
