Detailed Description
Template class for fixed-size encrypted integers.
This template provides convenient type aliases for common integer sizes (e.g., Eint8, Euint32). It inherits from Einteger and sets the bit size and signedness during construction.
- Template Parameters
-
T The underlying plaintext type (e.g., int8_t,uint32_t).BITS The number of bits for the encrypted integer. SIGNED True if the integer is signed, false otherwise.
The documentation for this class was generated from the following file:
- src/include/computefhe/Einteger.h
