Output:
362967911866744841 / 60 = 6049465197779081.00000000000000000000
6049465197779081.00000000000000000000 * 60 = 362967911866744832.00000000000000000000
num2 - num = 0.00000000000000000000

The error is that 362967911866744841 / 60 should be 6049465197779080.6833333333333333.
And also, 6049465197779081.00000000000000000000 * 60 is not equal to 362967911866744841 .

Due to this error, 362967911866744841 in Base 10 would be a1122334ef in Base 60, and K9XMIBhi09 in Base62x, but it will failed to reverse back from Base62x to Base 60 (a1122334ff).

Be careful in precision when dealing with extra long numbers!

中文测试 转换出来的是vBYjvfQ7vhMBwAx2L
去掉末尾一个两个三个字符只是末尾输出一个乱字符

如果去掉后面4个字符
如
echo Base62x::decode('vBYjvfQ7vhMBw');

死循坏了

Hi guys, does base62x has golang version?

Hi guys,
I need help by editing a few of sentences on Base62x in Wikipedia.org.
It would be an appendage to the page of Base64 in Wikipedia.org or a newly-created item on it.

I am trying to do so to help more developers know the better approach we have built to the traditional Base64.
The attempt had been made myself but failed due to that I am one of the authors of Base62x.

Could you please help on this addition of Base62x to Wikipedia?

Thanks in advance.

There is no license in this repo, so effectively all code is proprietary and we can't use it for anything...
