Data Structures
struct	idiv_return
	DIVAS signed division operator result output structure. More...
struct	uidiv_return

Functions
static void	divas_disable_dlz (void)
	Disables DIVAS leading zero optimization. More...

Call the DIVAS API Operation
In this mode, the way that directly call the DIVAS API implement division or mod operation.
int32_t	divas_idiv (int32_t numerator, int32_t denominator)
	Signed division operation. More...
uint32_t	divas_uidiv (uint32_t numerator, uint32_t denominator)
	Unsigned division operation. More...
int32_t	divas_idivmod (int32_t numerator, int32_t denominator)
	Signed division remainder operation. More...
uint32_t	divas_uidivmod (uint32_t numerator, uint32_t denominator)
	Unsigned division remainder operation. More...
uint32_t	divas_sqrt (uint32_t radicand)
	Square root operation. More...
DIVAS Overload '/' and '' Operation
In this mode, the user can transparently access the DIVAS module when writing normal C code. E.g. "a = b / c;" or "a = b % c;" will be translated to a subroutine call, which uses the DIVAS.
int32_t	__aeabi_idiv (int32_t numerator, int32_t denominator)
	Signed division operation overload. More...
uint32_t	__aeabi_uidiv (uint32_t numerator, uint32_t denominator)
	Unsigned division operation overload. More...
uint64_t	__aeabi_idivmod (int32_t numerator, int32_t denominator)
	Signed division remainder operation overload. More...
uint64_t	__aeabi_uidivmod (uint32_t numerator, uint32_t denominator)
	Unsigned division remainder operation overload. More...
