On 64 bit platform (unless `MRB_WORDBOX_NO_FLOAT_TRUNCATE`), float values are also packed in the `mrb_value`. In that case, we drop least significant 2 bits from mantissa.
On 64-bit platforms (unless `MRB_WORDBOX_NO_FLOAT_TRUNCATE`), float values are also packed in the `mrb_value`. In that case, we drop least significant 2 bits from mantissa.
If you need full precision for floating-point numbers, define `MRB_WORDBOX_NO_FLOAT_TRUNCATE`.
## NaN Boxing
NaN boxing packs the Ruby data in a floating-point numbers, which represent NaN (Not a Number) values. Under IEEE753 definitions every value that exponent is all set are considered as NaN. That means NaN can represent `2^51` values. NaN boxing is a teaching to pack the values in those NaN representation. In theory, 64 bits pointers are too big to fit in NaN, but practically most OS uses only 48 bits at most for pointers (except for some OS e.g. Solaris).
