Reporting Services :: If Divisor Is 0 Print Field Value But It Displaying Error

If divisor is "0" I need to print the Field, but for me it displaying #Error. If I pass any value it is working fine. It is not working only for the Field.

RULE: Fields!B.Value=0, PRINT Fields!A.Value.(IIf(B=0,A,A/B))

Working: IIF(Fields!B.Value=0,0,Fields!A.Value/IIF(Fields!B.Value=0,0,Fields!B.Value))

Not working:  IIF(Fields!B.Value=0,Fields!A.Value,Fields!A.Value/IIF(Fields!B.Value=0,Fields!A.Value,Fields!B.Value))

     A    B    Cal(A/B)
E   1    0        1
F   4    2        2
G   9    3        3
