如何忽略签名位? [英] How to ignore the signed bit?
问题描述
我有一个数字-569360386,并将其转换为十六进制格式。
我使用toString(16),我得到-21efc002。
但是怎么能得到0xDE103FFE,这是忽略最高位为
签名位?

I use toString(16),I get -21efc002.
But how can get 0xDE103FFE,which is to ignore the highest bit as the

那是关于Java,而不是Javascript!
-21efc002对我来说似乎没问题
=========== ===============
n = -569360386
document.write(n.toString( 16)+ '' <峰; br> ''); // -21efc002。
n = 569360386
document.write(n.toString(16)); // 21efc002。

That is about Java, not Javascript!
-21efc002 seems correct to me
==========================
n = -569360386
document.write(n.toString(16)+''<br>''); // -21efc002.
n = 569360386
document.write(n.toString(16)); // 21efc002.

那么有没有办法获得0xDE103FFE而不是-21efc002 ???
我必须使用自己的代码进行翻译吗?
Then is there any way to Get 0xDE103FFE but not -21efc002???
Must I use my own code to get translate it?
