Description
Converts a string that represents an integer (decimal or hex notation) into a number with error default.
StrToIntDef converts the string S, which represents an integer-type number in either decimal or hexadecimal notation, into a number. If S does not represent a valid number, StrToIntDef returns Default.
StrToIntDef supports strings in the following hexadecimal notations:
- Delphi: 0$1234 and 0x1234.
- C++: 0x1234.
Note: In Delphi, you can also use the C++ hexadecimal values notation, and use prefixes 0x or x indistinctly.
