int mbedtls_mpi::s |
Sign: -1 if the mpi is negative, 1 otherwise.
The number 0 must be represented with s = +1
. Although many library functions treat all-limbs-zero as equivalent to a valid representation of 0 regardless of the sign bit, there are exceptions, so bignum functions and external callers must always set s
to +1 for the number zero.
Note that this implies that calloc() or ... = {0}
does not create a valid MPI representation. You must call mbedtls_mpi_init().
