Arithmetic operation

RELU

Signed thresholding and ML-style activation flows.

Signature

Raw symbolsFHE16_RELU
Exampleint32_t* out = FHE16_RELU(a);

Caller

Signed thresholding and ML-style activation flows.

Circuit Path

Homomorphic pathSign-bit gated selection circuit: negative values map to encrypted zero, non-negative values pass through.

Input, Output, Ownership

Outputn-bit integer ciphertext.
OwnershipReturned ciphertext is caller-owned.
Implementation baselineFHE16Ver6/include/soAPI/soAPI.hpp and FHE16Ver6/src/soAPI/soAPI.cpp

C Example

int32_t* out = FHE16_RELU(a);
FHE16_Free(out);
