Simple formula using IF and SUM - yields unexpected error

Hello,
Using this formula for a bank account,
=IF(SUM(C2-A1+B1)=C1, "match", "NO match")
down a column of about 3000 rows,
yields only one cell with an unexpected and probably incorrect response in G2 with a "NO Match" - where the math is correct ?

Can someone please explain - I'm curious as to why this happens.
Thank you kindly,

A B C D
63.58 0.00 -54.97 match
64.57 0.00 8.61 NO match
128.21 0.00 73.18 match
201.39

in a bank account file, where "C2" is the previous balance, "C1" is the current balance,
"A1" is any check written, "B1" is any deposit applied.

This is an error that kreeps in from time to time. If you break down your formula to its basic part (you dont need to use SUM() for this)...=F3-D2+E2 press F2 and then F9, you will see the answer is 8.61000000000001

Change your formula to this, copied down...
=IF(ROUND(F2-D1+E1,4)=ROUND(F1,4), "match", "NO match")

Round to however many decimals you feel will give you what you need
