Is there anybody know how to optimization this equation in Integer Operation.

R' = Y' + 1.140*V'
G' = Y' - 0.394*U' - 0.581*V'
B' = Y' + 2.032*U'

and

R' = 1.164*(Y' - 16) + 1.596*(Cr' - 128)
G' = 1.164*(Y' - 16) - 0.813*(Cr' - 128) - 0.392*(Cb' - 128)
B' = 1.164*(Y' - 16) + 2.017*(Cb' - 128)


And I use floating point operation, but the result is different with IPP, the gap is just 1, therefore, I think this is round error, however, I don't know, How IPP round this equation?

Thanks very much.
