Text extraction using numbers MID()

I am trying to extract a text based on a cell containing a number set to 3 decimal places, ie. A1 = 7.140

I have been using the following formula - MID(A1,1,1)&MID(C13,3,3)&"0" which yields 7140.

The goal is to extract all four numbers sequentially excluding the decimal (it is used as an automated text feed for another long formula), ie. want:

7.142 => 7142
7.140 => 7140
7.700 => 7700

The problem is the formula above falls apart for the first and third example where 7.142 outputs 71420 and 7.700 outputs 770.

Is there any other function that can read the character 0?
