Introduction to parseint function parameter setting

The parseint function is often used to convert the string to int, and the parseint function has two parameters that can be set, where the second parameter can default

We often use the parseint function to convert a string to an int value, and the parseint function has two parameters that can be set, and the second argument can be default. parseint ("string", used in the system) Var num1=parseint ("2")//2 var num1=parseint ("Ten", 8)//8 var num1=parseint ("ten")//10 var   Num1=parseint ("10", 16)//16 parameters can be selected 16, 8, 10, 2 in-system. Usually we use 10, it is best to always use the second parameter, and set to 10, do not set the second parameter, the function itself to determine how to select the system. (problems may occur, such as "070" ECMAScript 3 considered to be octal ECMAScript 5 is considered decimal)
