Frequency bug?
Can someone explain to me why this happens?
This example is working.
FREQUENCY function returns {2; 1; 1}. 2 values (0.1 and 0.2) are equal to or less than 0.2. 1 value (0.3) is larger than 0.2 and equal or smaller than 0.3. 1 value (0.4) is larger than 0.3.
This example is not working as I thought it would.
FREQUENCY function returns {2; 0; 2} and I don´t understand why?
The formula in cell B8:B11 returns this array {0.1; 0.2; 0.3; 0.4}, exactly the same values as in B2:B5.
It seems to be the MOD function but why?
Why am I using the MOD function? To extract the fractional part of a number.

Hmm, seems like it's half Frequency's fault and half Mod's fault.
=MOD(1.3,1) causes the issue, but =MOD(2.3,1) does not. Yet =MOD(1.3,1)=0.3 returns true. Very interesting catch!
The same thing happens if I use INT function to extract the decimal part of a number.
Like this:
=1.1-INT(1.1)
=1.2-INT(1.2)
=1.3-INT(1.3)
=1.4-INT(1.4)
Both Excel 2010 and 2013 yields the same output.

It's our old friend the floating point error.

MOD(ROW(A13)/10,1)=0,3 is TRUE but
(MOD(ROW(A13)/10,1)-0,3) is 5,55111512312578E-17 but
MOD(ROW(A13)/10,1)-0,3 is 0
So, ROUND(MOD(ROW(11:14)/10,1),1) should work.
XLarium,
Thank you for commenting, I didn't know this.
I found this:

That explains why this happens.
