/* test_arith.cpp - Arithmetic operators of RecInt generic test file
Return value.
0 No error
!= 0 Bad result for an operation
The following constants have to be defined.
STD_RECINT_SIZE size of recint (> 5)
LOOPS number of loops of randized tests
RI_OP RecInt arithmetic operation (RI_add_nc, RI_sub_nc, RI_mul)
GMP_OP GMP arithmetic operation (mpz_add, mpz_sub, mpz_mul)
NOT_IN_PLACE (optional) the in-place tests do not occur [for addmul and div]
