In this tutorial we will show you the solution of JavaScript string to float 2 decimal, as there are many methods with the help of which we can hide elements by id in JavaScript.
Here, below we are going to show a couple of links in form of code in which we understand about the conversion.
Step By Step Guide On JavaScript String To Float 2 Decimal :-
One thing to note here that we have to convert string to float, but the float must have two decimals. Let us see the code.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>home page</title>
</head>
<body>
<h1>JavaScript string to float 2 decimal</h1>
<p>The parseFloat() Method</p>
<p>parseFloat() parses a string and returns the first number:</p>
<p id="demo"></p>
<script>
document.getElementById("demo").innerHTML =
parseFloat(343).toFixed(2) + "<br>" +
parseFloat("10").toFixed(2) + "<br>" +
parseFloat("7.33").toFixed(2) + "<br>" +
parseFloat("2 05 96").toFixed(2) + "<br>" +
parseFloat("its 100").toFixed(2);
</script></body>
</html>
- First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
- Secondly, the <html> tag is used to indicate the beginning of an HTML document.
- As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
- Here, then we create a body tag. All the content which we want to show on browser’s screen or display is always written inside this codes.
- Here, as you see that we create one heading, paragraph and then again paragraph. There is no meaning to use these all here. You can directly use script tag.
- Now, script tag is a paired tag with ending </script>. Our all JavaScript code is written under this pair of tags.
- One thing to note that there must be one paragraph or say anything there in body to show text from script tag.
- Inside script tag, first we target the paragraph which we created to show text/outputs from JavaScript. And parsefloat is used to convert string to float here whereas tofixed is used to give decimal at last. Here we give value 2.
- Hence, two decimals are showed there at last. Whereas prasefloat is used to convert string to float.
- You can customize decimals by changing value in toFixed. And parse float will give error if it is unable to found number at first in string.
- At last, the <body> and <html> tags are closed with </body> and </html> respectively.
Conclusion :-
At last in conclusion, here we can say that with the help of this article we are able to convert string to float with two decimals.
I hope this tutorial on JavaScript string to float 2 decimal helps you and the steps and method mentioned above are easy to follow and implement.
