In addition to the mathematical constants that can be accessed from the Math object there are also several methods available.
The following example uses the round() method of the Math object to round a number to the nearest integer:
| document.write(Math.round(4.7)); |
The code above will result in the following output:
| 5 |
The following example uses the random() method of the Math object to return a random number between 0 and 1:
| document.write(Math.random()); |
The code above can result in the following output:
| 0.6936874867631697 |
The following example uses the floor() and random() methods of the Math object to return a random number between 0 and 10:
| document.write(Math.floor(Math.random()*11)); |
The code above can result in the following output:
