Introduction to JavaScript Floating
The floating point is defined as the number which has the decimal numbers. It has been dynamically typed and most often the numbers are converted into the implicitly format between the strings and floating type of pointed numbers also these numbers are in the IEEE format and it has been the 64 bit format values to force the variable values is to been the floating point numbers. It has used the some global type of pre-defined methods in the script like parseFloat() is one of the pre-defined method. it has been used for the passing floating point of values in the variables in the script.
Syntax and Parameters
The javascript floating is one of the types of representing numbers in the application for using the mathematical operations in the web pages. It has their own features and behaviors in the operations.
<html>
<body>
<script>
var v=12345f;
var v1=123-4f5;
document.getElementById(“”).innerHTML=v + v1;
--some jaavscript logics---
</script>
</body>
</html>
The above codes are the basic syntax for mathematical operations in the scripts.We can use some default methods for reducing the lines of codes in the script because it helps to find the parses strings and it will return the numbers as floating point format.
How is Floating Done in JavaScript?
The Javascript sometimes we have to choose the features called Numeric conversion.It helps to use the operators and operands likeplus + or we can use as the functions or default methods like Number() is the strict format in script codes. If a value is not matching exactly the format numbers is to fail using the default methods called parseFloat.In technicallythe code, logic is to be supposed throw some exceptions like sole exception its one of the spaces fixed at the beginning or at the end of the string data types. sometimes its ignored in the applications but in some type of applications based on the requirements we often used the values in default formats like units, pixels, etc.These units are utilized the values like “203px” or “15pt” in presentation layers called CSS.
Generally the parseInt() and parseFloat() methodwill used as an optionally in second argument. Because it specifies the base of the numerical systemunder covers all types of numbers in the script.So it requires and it accepts the parseFloat method it can also be to parse each string of the number types for hexa numbers, binary numbers, octal numbers, and itcovers with all requirements.So that we can parse the parseInt and parseFloat numbers are the “read-only” options it cannot edit the numbers eventhough it has to be the string type until they can’t cover all segments. In case of an error, that time it handles the situationsfor gathering numbersand it is returned with different orders. The methods parseInt it returns the integer, while the parseFloat will return floating-point numbers it’s the basic difference of both functions of the javascript.

JavaScript has the built-in methods for classes like Math object which contains the small apilibraries of mathematical functions and constants.We can use these functions and default constants are moreover it applicable for both arithmetic and logical operations.Not only these functions it has some other default functions and constants all it has the default math object using these particular instances it applies the trigonometry and other features.
Examples of JavaScript Floating
Following are the examples as given below:
Example #1
Code:
<!DOCTYPEhtml>
<html>
<body>
<script>
x = parseFloat(" 107 ")
document.write('parseFloat(" 107 ") = ' +x +"<br>");
y = parseFloat("ramansiva57@gmail.com")
document.write('parseFloat("ramansiva57@gmail.com") = '
+y +"<br>");
c = parseFloat("geeksforgeeks@2018")
document.write('parseFloat("geeksforgeeks@2018") = '
+c +"<br>");
d = parseFloat("4.67")
document.write('parseFloat("4.67") = '
+d +"<br>");
e = parseFloat("02 8 2020")
document.write('parseFloat("02 8 2020") = '
+e +"<br>");
</script>
</body>
</html>
Output:
Example #2
Code:
<!DOCTYPEhtml>
<html>
<body>
<script>
x = parseFloat(" 107 ")
document.write('parseFloat(" 107 ") = ' +x +"<br>");
y = parseFloat("ramansiva57@gmail.com")
document.write('parseFloat("ramansiva57@gmail.com") = '
+y +"<br>");
c = parseFloat("geeksforgeeks@2018")
document.write('parseFloat("geeksforgeeks@2018") = '
+c +"<br>");
d = parseFloat("4.67")
document.write('parseFloat("4.67") = '
+d +"<br>");
e = parseFloat("02 8 2020")
document.write('parseFloat("02 8 2020") = '
+e +"<br>");
f=parseFloat(3.14);
document.write('parseFloat("3.14") = '
+f +"<br>");
g=parseFloat('3.14');
document.write('parseFloat("3.14") = '
+g +"<br>");
h=parseFloat(' 3.14 ');
document.write('parseFloat("3.14") = '
+h +"<br>");
i=parseFloat('314e-2');
document.write('parseFloat("3.14e-2") = '
+i +"<br>");
j=parseFloat('0.0314E+2');
document.write('parseFloat("0.0314E+2") = '
+j +"<br>");
k=parseFloat('3.14some non-digit numbers ad characters are also apploicables');
document.write('parseFloat("3.14") = '
+k +"<br>");
l=parseFloat({ toString: function() { return"3.14" } });
document.write('parseFloat("3.14") = '
+l +"<br>");
</script>
</body>

Conclusion
We have used the floating point of values in the web pages with different scenarios in scripting languages.Whenever we used the default method of the floating point of values it should be validated with the both client and server side most probably its been validating in client side.
