Excel/excel - quantity of odd and even numbers, in a range


Hello Tom,
I am working in Excel 2010

I am tyring to calculate how many odd and how many even numbers are within a range (ex 1-26), WITHOUT typing in each number individually like (1, 2, 3, 4, ...25, 26)

Ideally, I would like the range of numbers to be in one cell (1-26), or have a start cell (1) and an end cell (26).

Thank you in advance,


C1:  1-26   (cell formatted as Text so it doesn't get changed to a date)

for the number of Even:  =SUMPRODUCT(--(MOD(ROW(INDIRECT(SUBSTITUTE($C$1,"-",":"))),2)=0))

for the number of ODD:   =SUMPRODUCT(--(MOD(ROW(INDIRECT(SUBSTITUTE($C$1,"-",":"))),2)=1))

In excel 2007 and later, this will handle numbers as high as 1,048,576  since it uses the row function to produce an array of numbers expanded from your range 1-26.
