Supported Options

hex: true,          //when hexadecimal string should be parsed

eNotation: true,    //when number with eNotation or number parsed in eNotation should be considered
skipLike: /regex/   //when string should not be parsed when it matches the specified regular expression
infinity: "original", // "null", "infinity" (Infinity type), "string" ("Infinity" (the string literal))
unicode: false, //when number with unicode numerals should be parsed
