How to count numbers where the nth digit equals to a given number?
Supposing there is a number list in range B3:B11, to count the number of cells which the third digit equals to 5, you can apply the below formula.
Generic Formula
=SUMPRODUCT(--(MID(range,digit,n)="number"))
Arguments
How to use this formula?
1. Select a blank cell to output the result.
2. Enter the below formula into it and press the Enter key to get the result.
=SUMPRODUCT(--(MID(B3:B11,3,1)="5"))
Note: In this formula, B3:B11 is the column range contains the numbers you want to count, number 3 and 5 indicate you will check if the third digit of numbers equals to 5, you can change them based on your need.
How this formula works?
=SUMPRODUCT(--(MID(B3:B11,3,1)="5"))
- MID(B3:B11,3,1): The MID function finds the third digit from the middle of numbers in range B3:B11 and returns an array like this:{"0";"3";"3";"5";"5";"5";"0";"5";"1"}.
- {"0";"3";"3";"5";"5";"5";"0";"5";"1"}="5": Here compare each number in the array with “5”, if match, returns TRUE, otherwise, returns FALSE. You will get an array as {FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE}.
- --({FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE}): These two minus signs convert “TRUE” into 1 and “FALSE” into 0. Here you will get a new array as {0;0;0;1;1;1;0;1;0}.
- =SUMPRODUCT{0;0;0;1;1;1;0;1;0}:The SUMPRODUCT function sums all numbers in the array and returns the final result as 4.
