# numcodecs-zfp-classic
ZFP (classic) codec implementation for the [`numcodecs`] API.
This implementation uses ZFP's default [`ZFP_ROUNDING_MODE=ZFP_ROUND_NEVER`](https://zfp.readthedocs.io/en/release1.0.1/installation.html#c.ZFP_ROUNDING_MODE) rounding mode, which is known to increase bias and correlation in ZFP's errors (see <https://zfp.readthedocs.io/en/release1.0.1/faq.html#zfp-rounding>).
Please see the `numcodecs-zfp` codec for an implementation that uses an improved version of ZFP.
