How to do integer division in javascript (Getting division answer in int not float)?
提问by Nakib
Is there any function in Javascript that lets you do integer division, I mean getting division answer in int, not in floating point number.
Javascript 中是否有任何函数可以让您进行整数除法，我的意思是在 int 中获得除法答案，而不是浮点数。
var x = 455/10;
// Now x is 45.5
// Expected x to be 45
But I want x to be 45. I am trying to eliminate last digit from the number.
但我希望 x 为 45。我试图从数字中消除最后一位数字。
回答by Neeraj
var answer = Math.floor(x)
I sincerely hope this will help future searchers when googling for this common question.

var x = parseInt(455/10);
The parseInt() function parses a string and returns an integer.
The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
If the radix parameter is omitted, JavaScript assumes the following:
If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any other value, the radix is 10 (decimal)
parseInt() 函数解析一个字符串并返回一个整数。
radix 参数用于指定使用哪种数字系统，例如基数为 16（十六进制）表示字符串中的数字应从十六进制数解析为十进制数。
如果省略 radix 参数，JavaScript 假定如下：
If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any other value, the radix is 10 (decimal)
