| The number type deals with digits, It covers both floating point numbers and integers. |
| Floating point numbers are like – 412.562, 9.2, 0.468 |
| Integer numbers are like : 25, 1258, 968 |
| Initializing number type variables |
| Var age = 25 |
| Var is javascript keyword, age is a variable name, 25 is value assigned to age variable, variable age is of number type because the value assigned to age is of number type. |
| Var hra = 1585.56 |
| Var is javascript keyword, hra is a variable name, 1585.56 is value assigned to hra variable, variable hra is of number type because the value assigned to hra is of number type. |
| In the example given below we have used keyword document.write (messge ) which is used to print the message or variable value given with it. |
| Example |
| <html>
<head> </head> <body> <script type=”text/javascript”> var age=25; </script > </body> </html> |
| Understanding the program |
| <script > tag is the start of a javascript program, var is to declare a variable of name age and 25 is the value assigned to the variable age. document.write is used to print the given message and/or value of a given variable. We have used + sign here which is used to concatenate the message ( Age is : ) and the value of variable a (25). |
| Output of this program |
| Age is : 25 |
