2.13 MATH METHOD
In JavaScript, the Math object is a built-in object that provides a set of mathematical functions and constants.
It is not a constructor, meaning you cannot create instances of Math. Instead, it is a static object that allows
access to various mathematical operations.
Some of the Math methods are as follows:
Method Name Description Example
round() Rounds a number to the document.write(Math.round(3.68));
nearest integer. The round() document.write(“,” +Math.round
method rounds a number to (5.30));
the nearest integer, rounding
document.write(“,”+Math.round
up for decimals ≥ 0.5 and
(-8.78));
down for decimals < 0.5.
Output:
4,5,-9
random() Returns an arbitrary value document.write(Math.random());
between 0 (inclusive) and 1
Output:
(exclusive)
0.5492547873757196
max() Returns the largest number document.write(Math.max(-15,
-20));
document.write(“<br>”+Math.
max(150, 130, 120, 138));
Output:
-15
