Does Labview have function Mod() ?

[Kunsheng Chen]

Hello, everyone,

I am trying to parse an array only for all its odd/even number elements.  

I am thinking of use Mod function upon 'iteration' but labview seems have 

nothing there.   

Does anyone know something about that?  

Thanks in advance,

-Kunsheng

It's the Quotient & Remainder function on the numeric palette.

If you want to get the modulus of a number then use the quotient & remainder function in the numeric panel (block diagram).  Use the top input labelled X-Y8Floor(X/Y).  This is the mod().

The "Sign" function in the Numeric palette returns a "-1" for a negative number and a "1" for a positive number. If you multiply your non-zero number by the outcome of this function, your number is returned positive and this becomes essentially a Mod[number] function.

No, that is ABS(number).  MOD needs 2 inputs: the number and what the base is.  For instance MOD(3,2) is 1.  The easiest way to think of MOD is the remainder when you divide two numbers.

I found my way to this page because I was looking for a modulus function in the mathematical sense, i.e. In mathematics, the absolute value (or modulus) | a | of a real number is the numerical value of a without regard to its sign.

Interesting.  I never heard absolute value be called modulus before.  I just hit wikipedia to check.  In every sense I've heard of modulus (including a few math and cryptography classes), it is remainder (http://en.wikipedia.org/wiki/Modular_arithmetic).

I don't doubt your knowledge in this area, I was just defending my corner.

Save yourself the looping, why not just use decimate 1 D array?

Edit: Misread, you want the even/odd elements, not even odd indices.

That's because technically it's modulo, not modulus. Pesky mathematicians.
