◆ APSInt() [4/4]
|
explicit |
Construct an APSInt from a string representation.
This constructor interprets the string Str using the radix of 10. The interpretation stops at the end of the string. The bit width of the constructed APSInt is determined automatically.
- Parameters
-
Str the string to be interpreted.
