It is unlikely that you want to do what you indicated.  You showed the
decimal portion as an integer.  You would have to add some convention to
distinguish between numbers like 4.12345 and 4.012345  

The easiest convention is to keep the decimal point.


x = 4.12345;
IntegerPart[x]
FractionalPart[x]

4

0.12345
