Floor Vs Round Javascript

Difference between math floor and math round javascript i do not want an answer like.

Floor vs round javascript. 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 final rounded value depends on the fractional part. Math round rounds to the nearest integer if the fraction is 0 5 or greater rounds up math floor rounds down math ceil rounds up. Returns the smallest integer that is greater than or equal to the argument.

The ceil method rounds a number upwards to the nearest integer and returns the result. Towards the lesser value. When it comes to generating random numbers though math floor has a more even distribution than math round. Returns the smallest of the two arguments.

This method will resemble what you probably learned in school if you were paying more attention than me. Math floor x parameters x a number. Math floor always rounds down to the nearest integer while math round will round up or down depending on what side of 5 the number falls on. So the basic answer is that you use which one gets the result you expect.

It is the value which is to be tested for math floor. Javascript uses three methods to achieve this. 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. Returns the closed int or long as per the argument double or float.

If the passed argument is an integer the value will not be rounded. This method accepts single parameter asmentioned above and described below. Returns the largest integer that is less than or equal to the argument.
