Subtraction not working

Question

Hi, 
 I am facing issue with the below arithmetic operation. 
 
 300000 - sum(57594.61 , 25554.33 , 130364.39 , 49676.31 , 15783.03 , 21027.33) 
 The value of above expression should be 0, but i'm getting -5.820766e-011 as value when tested in expression rule. 
 Kindly assist if anyone knows any solution to this. 
 Thanks in advance.

yes, this works. 
 
300000 - tointeger(sum(57594.61 , 25554.33 , 130364.39 , 49676.31 , 15783.03 , 21027.33)) 
 
i believe there is some internal casting issue if we do it directly
