十六进制到十进制转换-PowerShell 5 [英] Hex to Decimal Conversion - PowerShell 5
问题描述
由于某种原因，当在PowerShell中将某些值从十六进制转换为十进制时，我得到了不正确的值.
For some reason, when converting some values in PowerShell from Hex to Decimal, I get incorrect value.
例如:-键入 0xC0000000 ，然后按Enter，您将得到 -1073741824 ，这是不正确的，正确的值为 3221225472 .给出的答案是我输入的负十六进制数的值 FFFFFFFFC0000000
For example:
- Type 0xC0000000 then hit enter, you'll get -1073741824 which is incorrect, the right value is 3221225472. The answer given is the value for the negative Hex number I entered FFFFFFFFC0000000
我认为这可能是一个解释问题，所以我明确要求将值从十六进制转换为Base10(十进制)，我仍然得到相同的错误答案 -1073741824 :
I thought this could be an interpretation issue so I explicitly asked to convert the value to from Hex to Base10 (Decimal), I still got the same incorrect answer -1073741824:
[Convert]::ToString(0xc0000000,10)
PowerShell为什么将 0xc0000000 解释为十六进制数字 c0000000 的负数?我在这里想念东西吗?
Why does PowerShell interpret 0xc0000000 as the negative for the Hex number c0000000? am I missing something here?
推荐答案
这是PowerShell陷阱(也存在于早期版本中).当您实际上希望该值是无符号整数时，该值将被解释为有符号整数.您需要像这样进行转换才能解决此问题:
That's a PowerShell gotcha (exists in earlier versions too). The value is interpreted as a signed integer when you actually want it to be an unsigned integer. You need to do the conversion like this to get around the issue:
[uint32]"0xC0000000"
