Increment by 1 for ttk scale

My problem is thatI Have a scale and a spinbox which change each other's values. OFr example if both go from 1 to 100, if I set the scale to 50, the spinbox will also change and vice versa. now I've got this to work pretty well except for one minor problem. I can't get the ttk scale to go up by whole numbers. Everytimer I change the scale, I get a ton of decimals behind my number. Here is my code:

def create_widgets(self):
"""my widgets"""
    spinval = IntVar()

    self.scale = ttk.Scale(self, orient = HORIZONTAL,
                                   length = 200,
                                   from_ = 1, to = 100,
                                   variable = spinval)
    self.scale.grid(row = 3,column = 1,sticky = W)


    self.spinbox = Spinbox(self, from_ = 1, to = 100,
                                   textvariable = spinval,
                                   command = self.update,
                                   width = 10)
    self.spinbox.grid(row = 3,column =3,sticky = W)

def update(self, nothing):
    """Updates the scale and spinbox"""
    self.scale.set(self.spinbox.get())

Now my question is: is it somehow possible to make it increment by whole numbers or change the graphic of the normal Tkinter scale so it looks better. Any help is welcome.

    self.scale.set(self.spinbox.get())
