Removing unwanted numbers after decimal point

=IF(ISERROR(A2*B2/C2+A2),"",(A2*B2/C2+A2))

The above formula works perfectly for my needs. However, I've tried to include the word "WON" in the answer cells (D) by including = "WON " & but as you can see some cells return answers with several numbers after the decimal point even though I've reduced the number to zero. Is there a way round this please?
Many thanks.
