Number -1 --> String "-1" ~
*octal*
Conversion from a String to a Number is done by converting the first digits to
! a number. Hexadecimal "0xf9", Octal "017", and Binary "0b10" numbers are
! recognized (NOTE: when using |scriptversion-4| octal is not recognized). If
! the String doesn't start with digits, the result is zero.
Examples:
String "456" --> Number 456 ~
String "6bar" --> Number 6 ~
String "foo" --> Number 0 ~
String "0xf1" --> Number 241 ~
String "0100" --> Number 64 ~
String "0b101" --> Number 5 ~
String "-8" --> Number -8 ~
String "+8" --> Number 0 ~
