Parse Float with 2 Decimals
In this article, I am going to show you how to print parse float with 2 decimals in javascript. To print parsfloat() value with 2 decimals, we need to use the “toFixed()” method after using the parseFloat() method.
parsFloat(value)
It converts a given value to a float number, if not possible to convert then it returns NaN.
toFixed(value)
It is used to return the given value to a fixed value. For example, If we give a float number “3.2342345” and set the toFixed() method to 2, it will return the first 2 decimal numbers like “3.23”.
Example code:
var a= parseFloat("12.345345");
var b=parseFloat("12.345345").toFixed(2);
document.write("Normal ParseFloat Method <br/>")
document.write(a, "<br/>");
document.write("Normal ParseFloat Method with 2 decimal <br/>")
document.write(b);
Output:
Steps:
- Here, we have created variable “a” and initialized value to String “12.345345”. So it will return the whole float value.
- Then we created variable “b” and initialized the value to string “12.345345” then we use the toFixed(2) method. So it will return the first 2 decimals.
