1.1 Introduction
A Math object is a mathematical object that provides mathematical calculations for data, such as getting absolute values and getting rounded up. No constructor and
In js, Math functions can include various methods, such as Math. random (): Math. round (); Math. floor (); and Math. ceil (); opposite, Math. floor (); let me introduce it later.
Math functions are mainly used to process numbers.
Math. random ():
Some Math object methods can implement some mathematical calculations in our textbooks. The following are commonly used methods:
1. Math. min () and Math. max () return the minimum and maximum values of the parameters respectively.
Example:
Alert
1. Math. min () and Math. max () return the minimum and maximum values of the parameters respectively. Example:Alert (Math. min (1, 2, 3) // output "1"Alert (Math. max (1, 2, 3) // output "3"2. Math. abs () returns the absolute value of the
