Why can't you just divide by 100?
What do you mean by "fixed" and "manipulated"? What do you want the TFloatSpinEdit to do?
TUpDown allows you to stretch the arrows, orientate them around a TEdit etc. The FloatEdit allows none of this. It might allow changing arrows to the left of its own edit but apart from that, you are unable to change it.
TUpDown has a facility to asscociate with an object, like a binding. When you use this, it restricts you to integers for the increment. You can add your value to the increment but the resultant value must be of type integer, TFloatSpinEdit by virtue, doesn't.
