Does Labview have function Mod() ?

Makes me want to tell the jokes about how mathematicians give accurate information that is useless or makes no real sense...

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.

FYI, LabVIEW does have an absolute value function in the numeric palette as well so you don't need to create one that way.

Kunsheng,

the and primitive may be your friend here. It will return 1 for every odd number an 0 for every even number.

You can also unleash it on the whole array - no iterations necessary!

Florian, the original post is over three years old so I imagine the point is moot by now...   Good point though!

[Florian.Ludwig]

Now that you mention it.

I just didn't look at the date of the original post - and from the fourth post on they're all very recent.

When using integer maths, the better solution is to use the expression node (in the numeric functions palette).

e.g.     x%5

This is much faster than using the quotient remainder, as it is a single clock cycle (no divisions and multiplications internally).

e.g. to find odd/even integers   x%2   then have a case for 0  or not zero

Very strange that mod is not visible as a numeric function in LabView.... I guess it is a slip up by NI

Forgot to mention:

mod  is not equivalent to remainder   (mod can give -ve results for -ve values....... ..... but remainder is always positive)
