long int idivlr(long fract, long fract);
int idivk(accum, accum);
long int idivlk(long accum, long accum);

unsigned int idivur(unsigned fract, unsigned fract);
unsigned long int idivulr(unsigned long fract, unsigned long fract);
unsigned int idivuk(unsigned accum, unsigned accum);
unsigned long int idivulk(unsigned long accum, unsigned long accum);
```
