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
