These functions assign values to elements. When integers are assigned, they are mapped to algebraic structures canonically if it makes sense (e.g. rings and fields).
void element_set0(element_t e)
Set e to zero.
void element_set1(element_t e)
Set e to one.
void element_set_si(element_t e, signed long int i)
Set e to i.
void element_set_mpz(element_t e, mpz_t z)
Set e to z.
void element_set(element_t e, element_t a)
Set e to a.
