| sc_int.h -- A sc_int is a signed integer whose length is less than the |
| machine's native integer length. We provide two implementations |
| (i) sc_int with length between 1 - 64, and (ii) sc_int with |
| length between 1 - 32. Implementation (i) is the default |
| implementation, while implementation (ii) can be used only if |
| the class library is compiled with -D_32BIT_. Unlike arbitrary |
| precision, arithmetic and bitwise operations are performed |
| using the native types (hence capped at 32/64 bits). The sc_int |
| integer is useful when the user does not need arbitrary |
| precision and the performance is superior to |
| sc_bigint/sc_biguint. |
