Description
Converts a string that represents an integer (decimal or hex notation) into a number.
StrToUInt64Def converts the string S, which represents an integer-type number in either decimal or hexadecimal notation, into a number. The output value is an unsigned 64 bit sized integer. If S does not represent a valid number, StrToUInt64Def returns the number passed in Default.
StrToUInt64Def supports strings in the following hexadecimal notations:
- Delphi: 0$1234 and 0x1234.
- C++: 0x1234.
