+ parseFloat(str) works similar to JavaScript but returns 3 results (number, is whole string parsed, characters parsed)
* toNumber(mixed[, radix]) converts string to number, doesn't support special prefixes anymore (0x, 0b and so on)
* numberOf(mixed) returns argument if the argument is number else null
* stringOf(mixed) returns argument if the argument is string else null
* booleanOf(mixed) returns argument if the argument is boolean else null
