A simple gem providing methods to pack floating point numbers using the half-precision IEEE 754 FP16 format (big endian and little endian) as well as corresponding unpack methods.
The actual floating point operations are done using the Half Rust crate via a native extension.
irb(main):006>require "fp16_pack"
=> true
# Little-endian packing
irb(main):007> Fp16Pack.pack([1.000, 0.0005, Float::INFINITY])
=> "\x00<\x19\x10\x00|"
irb(main):008> Fp16Pack.unpack(_)
=> [1.0, 0.0005002021789550781, Infinity]
irb(main):009> Fp16Pack.pack_be([1.000, 0.0005, Float::INFINITY])
=> "<\x00\x10\x19|\x00"
irb(main):010> Fp16Pack.unpack_be(_)
=> [1.0, 0.0005002021789550781, Infinity]
