I'm hoping to see something like the above mod function in Phobos someday.
I'd like that, for both int/long/BigInts. And I'd like some functions for
BigInts:
- divmod: returns both % and div and %, but it's more efficient if you need
both values;
- gcd
These should both exist for int and long as well.
Consider the following program:
int div(int a, int b)
{
auto x = a / b;
auto y = a % b;
return x + y;
}
Compile with:
dmd -c test -O
Disassemble with obj2asm:
_D4test3divFiiZi comdat
push EAX
mov EAX,8[ESP]
cdq
idiv [ESP]
add EAX,EDX
pop ECX
ret 4
