How to remove the remainder in javascript

The parseInt() function can parse a string and return an integer.

When the value of parameter radix is 0, or the parameter is not set, parseInt() will determine the base of the number based on string.

When the parameter radix is omitted, JavaScript defaults to the radix of numbers as follows:

If string starts with "0x", parseInt() will parse the rest of string into hexadecimal integers.

If string starts with 0, then ECMAScript v3 allows an implementation of parseInt() to parse the following characters into octal or hexadecimal numbers.

If string starts with a number from 1 to 9, parseInt() will parse it into a decimal integer.

Syntax

parseInt(string, radix)
