Description
Converts a string that represents an integer (decimal or hex notation) into a number.
StrToInt converts the string S, which represents an integer-type number in either decimal or hexadecimal notation, into a number.
S must be an integer number, in either decimal or hexadecimal (see below) notation, with an optional sign ("-" or "+") at the beginning. Decimal or thousand separators are not supported. If S does not represent a valid number, StrToInt raises an EConvertError exception.
StrToInt supports strings in the following hexadecimal notations:
- Delphi: $1234
- C++: 0x1234
Note: In Delphi, you can also use the C++ hexadecimal values notation, and use prefixes 0x or x indistinctly.
