Rounding of Numbers
Rounding is one of the most frequent operations on the numbers. JavaScript provides several built-in functions for rounding which are given in the below table.
| Function | Description | Example |
Math.floor() | Rounds off to the lower limit | 3.1 becomes 3, and -1.1 becomes -2. |
Math.ceil() | Rounds off the number to the upper limit | 3.1 becomes 4, and -1.1 becomes -1. |
Math.round() | Rounds off the nearest integer when value is equal or greater than .5 | 3.1 becomes 3, 3.6 becomes 4, and 3.5 rounds up to 4 (the middle case) |
Task
A variable named price with the assigned value of 4.7 has been given to you. Your task is to round off this variable such that we get 4 as the output.
