Random number generator. Even and odd numbers

[Mr_Lordi]

I have a problem.

I have a random number generator, it goes from 0 to 20, I need to have two indicators, one will show how many numbers are pairs, and how many are not.

I tried to use the decimated 1D array, but since those numbers are random, it doesn´t work for me. I´m new with LabView, and I don´t know if there is some other way to make it work, I need some help, especially with some examples.

Thank you so much.

Hi,

Your thread title says "Even and Odd numbers", but your description of the problem states 'pairs'.

Can you clarify exactly what you are trying to do.

Thanks

What do you mean by "pairs"?  Just that a number is duplicated or that you have two of the same number back to back?

Hi.

I need to indicate how many numbers are even and how many are odd

Thanks.

I don't think your issue is necessarily with LabVIEW, although your unfamiliarity with it might distract you from what you really need to do.  Have you thought up of how you would do it on paper yet?  Maybe base your sorting on whether or not dividing by two leaves a remainder?

Create the array.  Use quotient remainder to divide by 2.  Now you have an array where all the odd numbers are now 1, and all the even numbers are now 0.  Sum the array and you have the total number of odd numbers.  The number of evens will be the length of the array divided by the # of odds.

Haha I lost sight of the fact that he was looking for the amount off odds and evens.  Good one.

Typically it is more efficient to do a bitwise AND with 1. You get zero for even and one for odd.

How are you generating the random numbers?

"The number of evens will be the length of the array divided by the # of odds."......you mean subtracted not divided?
