function StrToIntDef(const S: string; Default: Integer):Integer;
The StrToIntDef function converts an Integer string, S such as '100' into an Integer value, with a Default if the conversion fails.
It supports +ve and -ve numbers, and hexadecimal numbers, as prefixed by $ or 0x.
Example
var
firstNumber,secondNumber, thirdNumber, fourthNumber : Integer;
{
firstNumber = 32;
secondNumber = StrToIntDef('test00', 10); // Leading blanks are ignored
thirdNumber = StrToIntDef('$1E', 0); // Hexadecimal values start with a '$'
fourthNumber = StrToIntDef('-0x1E', 0); // ... or with a '0x'
ShowMessage('firstNumber : '+IntToStr(firstNumber));
ShowMessage('secondNumber : '+IntToStr(secondNumber));
ShowMessage('thirdNumber : '+IntToStr(thirdNumber));
ShowMessage('fourthNumber : '+IntToStr(fourthNumber));
}
Output:
firstNumber : 32
secondNumber : 10
thirdNumber : 30
fourthNumber : -30
