Chapter 4. Element functions
z must be an element of a integer mod ring (i.e. Z n for some n). Set c = a z, that is a + a + . . . + a where there
are z a’s.
void element_div(element_t n, element_t a, element_t b)
Set n = a / b.
void element_double(element_t n, element_t a)
Set n = a + a.
void element_halve(element_t n, element_t a)
Set n = a/2
void element_square(element_t n, element_t a)
Set n = a 2
void element_neg(element_t n, element_t a)
Set n = -a.
void element_invert(element_t n, element_t a)
Set n to the inverse of a.
