IntToHexStr
Description
Convert an integer to a hexadecimal string.
Parameters
| Name | Direction | Description |
|---|---|---|
value |
in | Integer to convert. |
Success
Returns a Str holding the base-16 textual form of value with lowercase letters, bound to value’s allocator. value is not modified.
Failure
Returns an empty Str bound to value’s allocator when the underlying IntToStrRadix fails (intermediate allocation failure). The caller cannot distinguish that from a true empty result; use IntTryToStrRadix directly when failure detection is required.
