How to compare only decimal parts of two numbers in Excel?
If you have two columns of numbers with decimal places and need to compare only the decimal portions, Excel provides methods to achieve this without manually checking each number. This tutorial covers two ways to quickly compare decimal parts only: using formulas to ignore the whole number portion and the Extract Text feature in Kutools for Excel to isolate decimals.

To compare the decimal numbers between two numbers, you can apply the following formulas as needed.

Note: In above formula, A1 and B1 are the two numbers you want to compare, 0.01 indicates to compare decimal numbers by two digits.
Tip: If you want to round the decimal firstly and then compare, you can use one of following two formulas.
In the formulas, 2 indicates to compare first two digits in decimal numbers, A1 and B1 are the numbers you want to compare.
=IF((ROUND(A1,2)-ROUND(B1,2))=0,1,-1)
=IF(ROUND(A1,2)=ROUND(B1,2),"ok","!!ERROR!!")
Compare two decimal numbers with Extract Text
If you want to compare decimal numbers by only the first two or first n digits, you can apply the Extract Text utility of Kutools for Excel to extract the decimal numbers you need first, and then use a simple formula to compare them.
1. Select the two columns of numbers you want to compare, and click Kutools > Text > Extract Text. See screenshot:
2. In the Extract Text dialog, type .?? into the Text box, and click Add to add this criterion into the Extract list. See screenshot:

3. Only check the new criterion in the Extract list section, and click Ok. Then select a cell to place the extracted decimal numbers, and click OK to finish. See screenshot:
4. In the adjacent cell to the extracted numbers, type this formula =IF((D1-E1)=0,1,-1), type Enter key, and to drag fill handle down to the cells you need. In the results of calculations, 1 indicates the two numbers are the same, -1 shows the numbers are different. See screenshot:
