nancryption
nancryption encodes float32 values into float64 quiet-NaN bit patterns and decodes them back again. This is useful when you need to smuggle a 32-bit payload through a float64-only path while still tagging values as NaN.
Install
uv sync
Quick Start
import numpy as np
from nancryption import nancrypt, nandecrypt
payload = np.array([1.0, -2.5, np.pi], dtype=np.float32)
encoded = nancrypt(payload)
decoded = nandecrypt(encoded)
print(encoded.dtype) # float64
print(np.isnan(encoded).all()) # True
print(np.array_equal(decoded, payload)) # True
API
nancrypt(a: np.ndarray) -> np.ndarrayEncodes float32 payload bits into float64 quiet NaN values.nandecrypt(arr: np.ndarray) -> np.ndarrayRecovers the embedded float32 payload from encoded float64 values.
