Programming the INT and FRAC functions

On the HP-55, for INT you can do :

Code:

g H.MS g H.MS EEX 9 + f LastX -

And for FRAC :

Code:

ENTER g H.MS g H.MS EEX 9 + f LastX - -

This works for positive numbers but not for negative ones and I'm not sure it fits your definition of "short and effective"...
