    Re: Mystery bug

    Yes ok.
    The loop variable rhd% I mean went up to 71 - or more if I let it.
    The code in between is big but unrelated rather than not.
    I 'll try again and post.

    Mystery bug

    I wrote a small program like this:

    For rhd% = 1 to 2

    < some routine

    text.text = str$(i%) + other indices internal to the routine >

    next rhd%

    Re: VB6 arithmetic issue

    No I 'm not calling the commands in the immediate subroutines.
    The exact code is too big. I was only debugging where the x,y,z are calculated.
    But what can I do to see the hidden decimals in both...

    Re: VB6 arithmetic issue

    Well first does it do the same to you ?
    I don't know how many digits really I need. Perhaps two is ok but we are talking about the error.
    What baffles me most is why two separate subroutines using...

    Similar behaviour is observed with (x-y)/z, before the exponentiation.

    Re: VB6 arithmetic issue

    Also I have two independent subroutines doing the same thing.
    The T values I designate as (1) in my previous post come out different in the 6th decimal place !

    VB6 arithmetic issue

    I 'm trying to solve a mathematical problem and using VB6 my code computes three numbers x, y, z.
    Their values are x = 88.04261, y = 86.39919, z = 0.6955 in single precision.

    Now the final...

    Re: Is vb6 precise enough ?

    It's simle to test.
    Select 10,000 random numbers and put them into an array x() and another 10,000 and put them into another array y().
    Then compute Ztotal with the two methods.
    Then the same with...

    Re: Is vb6 precise enough ?

    If you want to perform a test set {x}= a set of 10,000 random values from 0 to 7, precision two decimal digits.
    For {y} similarly.
    Also say A = 0.5, B = 0.5, m = 2, n = 2 (or with the exp function...

    Re: Is vb6 precise enough ?

    I don't know the result.
    You think it's the single precision creating errors ?
    If so which of the two formulations is more susceptible:

    exp(-a*x^m - b*y^n)

    or

    A^(x^m) + B^(y^n) ?

    Re: Is vb6 precise enough ?

    χ-y 0 to 5 say. m,n 0.5 to 3 say.
    a, b who knows ? But their equivalents 0 to 1.

    Now is it single precision the culprit and would double precision help ?

    I 'm into some instrument calibration programming and involves a quantity of the following type:

    Greek in vb6

    I don't seem to have any Greek in the development environment, in the code window, immediate window.
    Why ?
    In my old installation I could use Greek.

    I have a test program running now and I can't...
