Generating Random Numbers Between 0.000 and 100.000

    Hi Folks - I hope you can help. I am writing a chemistry program and have to generate random numbers between 0 and 100 with 3 decimal places. I tried using the RRandom command in the Expression Editor, but I only get whole numbers.
    I solved the problem, but want to know if there is an easier solution.
    Here is my solution...
    I created 3 counters called IntPart, DecPart, TotalNum
    I created 3 strings called IntString, decString, TotalString
    Using the Random command I create the IntPart value between 0 and 100 and then I create the DecPart value between 0 and 1000.
    Then using the Str$ command, I convert each counter to a string (setting the Alterable Strings).
    Then I combine the IntString and the DecString with a decimal inbetween to produce a the TotalString.
    Finally, I convert the TotalString to a number with the Val command in the TotalNum counter .
    Is there a more direct way to get these random numbers?
    Thanks for your time.

    Isn't there the possibility of adding 1 using that setup? Because 1000/1000.0 would return 1. Maybe this instead: RRandom(0,100) + (RRandom(0,999)/1000.0). It will only return 100.999 worst case. And if you want to only return between 0-100 and not 100.999, then use this: Min(RRandom(0,100) + (RRandom(0,999)/1000.0),100)

    dividing by 1000.0 casts it into a float even if the math would result in a whole integer.
    for example, 1000/1000.0 = 1.000, instead of 1

    if you want to change a number into a float without much hassle, you can always just add a {*1.0} to an expression. Once a number is a float, any further expressions with it as a parameter will turn the results of math with it into floats, unless you cast it back to an integer using functions like int(), ceil(), floor() or round()

    [MENTION=5821]Pixelthief[/MENTION] I see. Thank you for that info.

    What I was referring to was the possibility of the expression returning 101, however. Would Min(x, 100.000) work in my solution?
