The only built-in formula that comes to my mind is
REST(Dividend;Divisor) in German. In English this should be
MOD(Dividend;Divisor). But it still has the Problem with the sign of
the Dividend.
For example:
The number in Cell B2 is 4.3459234, your formula should be =3DMOD(B2;1)
The number in B2 is 4.3459234, then the formula should be =3DMOD(B2;-1)

To overcome this you could use the built-in formula VORZEICHEN(), in
English SIGN().
 In the example:
=3DMOD(B2;SIGN(B2)

Not really an improvement, just another way.

Maybe it helps you anyway.
