Description

Converts a string that represents an integer (decimal or hex notation) into a number.

StrToUInt64 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, StrToUInt64 raises an EConvertError exception.

StrToUInt64 supports strings in the following hexadecimal notations:

  • Delphi: 0$1234 and 0x1234.
  • C++: 0x1234.
