Random Number Generation And Integer Return

Recommended Posts

Hi There,


I am working on a problem where i require a script to randomly generate a number between 1 and 3. I have used the function randuniform(1,3,1), however, this generates numbers with a huge number of decimal places. I only require the integer. 


I am curious to know if DAQFactory has an integer conversion function (like Int() ), i have seen the rounding functions however i don't want to add any bias. Can you suggest a way to output an integer without converting to a string parsing the string and reconverting the string back to an integer?

Sure, use floor() or ceil().  Floor() will strip the decimal.  Ceil() will do the same as floor(), but add 1.  So:


floor(1.234) = 1

ceil(1.234) = 2


Note that there is only one integral number BETWEEN 1 and 3 :)   Also, note that if you use floor(), which I suggest, you'll want randuniform to go from 1 to 3.9999, not 1 to 3, otherwise you'll basically never get 3.  So:
