How to convert cardinal to unsigned string representation

votes

I have a dll routine that returns a UInt32. I gather that the Delphi cardinal type is equivalent to this type. I'd like to display the UInt32 value as a string. However inttostr () assumes the argument is a signed Int32 so it will sometimes return a string that has the appearance of a negative value. Is there a way to convert a cardinal into its unsigned string representation?

Using XE6.

Is there not UintToStr? – LU RD
Which Delphi are you using? – SilverWarior
Didn't spot uinttostr, and I've been looking...and it worked. – rhody
Good, you can make that an answer. – LU RD
IntToStr() has an Int64 version, not just an Integer version. Also, Delphi 2009 and later have an actual UInt32 type, you should use that instead of Cardinal. – Remy Lebeau

To convert a UInt32 integer type into the unsigned string equivalent use the method UIntToStr.

For example:

value : UInt32;

value := 4294967294;
str := UIntToStr (value);
// str now equals '4294967294'
