支持的选项
hex: true, //when hexadecimal string should be parsed
leadingZeros: true, //when number with leading zeros like 08 should be parsed. 0.0 is not impacted
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
