]] XL-mania [[ fungsi LEN, SUBSTITUTE, SUMPRODUCT, SUM,...

 

Dear Master-Master Excel...

Saya ada sdikit problem nih .....

data misalkan data di L14 ...> sd34
1>  =SUBSTITUTE(L14,{0,1,2,3,4,5,6,7,8,9},"")                                                                      rumus ini menghasilkan              sd34                                           maksudnya gmn... minta fenjelasan
2>  =LEN(SUBSTITUTE(L14,{0,1,2,3,4,5,6,7,8,9},""))                                                            rumus ini menghasilkan                   4                                               karena memang jumlah huruf 4
3>  =LEN(L14)                                                                                                                          ...................................                   4                                               karena memang jumlah huruf 4

ketika hasil di atas dimasukkan ke rumus di bawah ini
  = SUMPRODUCT(LEN(L14)-LEN(SUBSTITUTE(L14,{0,1,2,3,4,5,6,7,8,9},"")))            
  = SUMPRODUCT(4-4)    => 0

tapi kalau langsung
=SUMPRODUCT(LEN(L14)-LEN(SUBSTITUTE(L14,{0,1,2,3,4,5,6,7,8,9},""))) => 2

Minta penjelasan kenapa bisa terjadi perbedaan hasil....?
sebenarnya fungsi LEN, SUBSTITUTE,  SUMPRODUCT, SUM,... ada yang beda dari help excel nggak ya,...?

=SUM(LEN(L14)-LEN(SUBSTITUTE(L14,{0,1,2,3,4,5,6,7,8,9},""))) => 2
Apakah fungsi SUM = SUMPRODUCT ?
