COUNT command with a column of numbers

Suppose that I have a column of numbers in of this shape:

22 100,10

-78,00

Now, I need a command containing the key-word =COUNT which would count the number of occurrences
of the numbers equal to -78. What this command should be ?

retag because obviously its not about math but calc

Hello

assuming

A1 contains 22
A2 contains 100,10
A3 contains -78

use: =COUNTIF(A1:A3;-78)

It works fine, thank you. BTW how do I compute the real number 2/3 so that the output would be 0.6666667 within a cell? I’ve tried /,div,divide,division with no success.

Use =2/3

Why do you mention “closing the question” in your last comment ? I wouldn’t do that, someone else is considering to do it ? Thank you for an explanation, I’m quite new here.

Why do you mention “closing the question” in your last comment ?

Were do your read that from "Use =2/3", which is my last comment? There is no need to close a question (I’m not the author of any automatic email you may receive from the system)

There was written “there is no need to close the question” some seconds ago in that comment …just below =2/3
