#### How to count only whole numbers in Excel

As the below screenshot shown, there is a product sales table, to count only the whole numbers in the Sales column, you can do as follow to achieve it.

Generic Formula

=SUMPRODUCT(--(MOD(range,1)=0))

Arguments

Range: The range of cells you want to count whole numbers.

How to use this formula?

1. Select a blank cell to place the result.

2. Enter the below formula into it and press the Enter key to get the result.

=SUMPRODUCT(--(MOD(E3:E17,1)=0))

How this formula works?

=SUMPRODUCT(--(MOD(E3:E17,1)=0))

• 1) MOD(E3:E17,1): Here use the MOD function to test for whole numbers in E3:E17. It returns the remainders after each number in range E3:E17 is divided by 1: {0.35;0;0;0;0;0.35;0;0.98;0;0;0.80;0;0;0.75}.
• 2) {0.35;0;0;0;0;0;0.35;0;0.98;0;0;0.80;0;0;0.75}=0: Compare each number in the array with 0, and returns a TRUE FALSE array like this: {FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE;TRUE;TRUE;FALSE;TRUE;TRUE;FALSE }. In this array, TRUE values represent a whole number, and FALSE values represent a decimal number.
• 3) --{FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE;TRUE;TRUE;FALSE;TRUE;TRUE;FALSE}: These two minus signs convert “TRUE” into 1 and “FALSE” into 0. Here you will get a new array as {0;1;1;1;1;1; 0;1;0;1;1;0;1;1;0}.
• 4) SUMPRODUCT{0;1;1;1;1;1; 0;1;0;1;1;0;1;1;0}: The SUMPRODUCT function sums all numbers in the array and returns the final result as 10.

#### How to sum only whole numbers in Excel

To sum only whole numbers in a specified range of cells, you can do as follows.

Take the above product sales table as an example.

Generic Formula

=SUMPRODUCT(--(MOD(range,1)=0)*range)

Arguments

Range: The range of cells you want to sum whole numbers.

How to use this formula?

1. Select a blank cell, enter the below formula into it and then press the Enter key to get the result.

=SUMPRODUCT(--(MOD(E3:E17,1)=0)*E3:E17)

How this formula works?

=SUMPRODUCT(--(MOD(E3:E17,1)=0)*E3:E17)

• 1) MOD(E3:E17,1): Here use the MOD function to test for whole numbers in E3:E17. It returns the remainders after each number in range E3:E17 is divided by 1: {0.35;0;0;0;0;0.35;0;0.98;0;0;0.80;0;0;0.75}.
• 2) {0.35;0;0;0;0;0;0.35;0;0.98;0;0;0.80;0;0;0.75}=0: Compare each number in the array with 0, and returns a TRUE FALSE array like this: {FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE;TRUE;TRUE;FALSE;TRUE;TRUE;FALSE }. In this array, TRUE values represent a whole number, and FALSE values represent a decimal number.
• 3) --{FALSE;TRUE;TRUE;TRUE;TRUE;TRUE;FALSE;TRUE;FALSE;TRUE;TRUE;FALSE;TRUE;TRUE;FALSE}: These two minus signs convert “TRUE” into 1 and “FALSE” into 0. Here you will get a new array as {0;1;1;1;1;1; 0;1;0;1;1;0;1;1;0}.
• 4) SUMPRODUCT({0;1;1;1;1;1;0;1;0;1;1;0;1;1;0}*E3:E17): Here each number in the array multiplies numbers in range E3:E17 to get the result as this: SUMPRODUCT(0;2028;900;3944;2757;1231;0;2313;0;3152;1361;0;1980;2579;0), and then the SUMPRODUCT function sums all numbers in the array and returns the final result as 22245.
