512 numbers. 512 (floating point) numbers.
513
514 If the number consists of digits only, JSON::XS will try to
515 represent it as an integer value. If that fails, it will try to
516 represent it as a numeric (floating point) value if that is possible
517 without loss of precision. Otherwise it will preserve the number as
518 a string value.
519
520 Numbers containing a fractional or exponential part will always be
521 represented as numeric (floating point) values, possibly at a loss
522 of precision.
523
524 This might create round-tripping problems as numbers might become
525 strings, but as Perl is typeless there is no other way to do it.

515 These JSON atoms become "JSON::XS::true" and "JSON::XS::false", 528 These JSON atoms become "JSON::XS::true" and "JSON::XS::false",
516 respectively. They are overloaded to act almost exactly like the 529 respectively. They are overloaded to act almost exactly like the
517 numbers 1 and 0. You can check wether a scalar is a JSON boolean by 530 numbers 1 and 0. You can check wether a scalar is a JSON boolean by
