After much findings, this works for me:

# Connection Signals

# When user tweaks using the slider
self.slider.valueChanged[int].connect(self.update_spinbox)
# When user modify via the spinbox
self.spinbox_value.editingFinished.connect(self.update_slider)


# Functions for each modication made towards slider and spinbox
def update_slider(self):
    # spinbox_value uses float/ doubles type
    # '*100' is used to convert it into integer as QSlider
    # only register integer type
    spinbox_value = self.spinbox_value.value() * 100
    self.slider.setSliderPosition(spinbox_value)

def update_spinbox(self, value):
    # QSlider only uses integer type
    # Need to convert the value from integer into float
    # and divides it by 100
    self.spinbox_value.setValue(float(value) / 100)
