Float To Integer

I'm creating a user form where the user can enter latitude and longitude in either Deg/Min/Sec format or Decimal Degrees. To go from decimal degrees into Deg/Min/Sec I need to do the following

A=Decimal Degrees (Single)
X=Degrees (Integer)
Y=Minutes (Integer)
Z=Seconds (Single)

X = Integer(A) <-- I need to cast A as an integer or truncate it. Not sure how to do this in VBA. Y = Integer[( A - X ) * 60] <-- Again, needs to be cast as an integer Z = {[( A - X ) * 60] - Y} * 60. I didn't see a native truncate function in Excel and in the past I've always used Left() or Right()
