Javascript Math Floor Math Random

Then by taking the math floor we take an integer number in range 0 10 since math floor returns the largest integer less than or equal to a given number.

Javascript math floor math random.

The math floor method is used to round off the number passed as a parameter to its nearest integer in downward direction of rounding i e. Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor. The max min 1 is the logic that creates the range. If the passed argument is an integer the value will not be rounded.

The floor method rounds a number downwards to the nearest integer and returns the result. This method accepts single parameter asmentioned above and described below. When you add the min at the end you are adding the 2 to your range and end up with a random number from 2 to 10. It cannot be chosen or reset by the user.

The math random function returns a floating point pseudo random number in the range 0 to less than 1 inclusive of 0 but not 1 with approximately uniform distribution over that range which you can then scale to your desired range. There is a 1 with math random so it will always going to add 1 to the randomly generated number. You can just randomly generate a number since math random will generate any floating number between 0 1 then use if. Math floor math random max min 1 is generating a whole number between the range of 0 to 8.

Example math floor math random 10. Adding one to this expression result in a number in the range 1 11. Math floor x parameters x a number. A number representing the largest integer less than or equal to the specified number.

Towards the lesser value.
