Excel adding numbers wrong ?

[RompStar]

Why is Excel adding the numbers wrong ?

The true answer is 7,274.87, but AutoSum is giving me 7,274.89 or 2 cent more.

I tried accounting, currency, general and number formatting and it's still adding it wrong, or what am I doing wrong ?

I added it in calculator in Windows and regular calculator and I get the .87 not .89, what could be wrong ?

Please help.
