Title: min() and max()
Post by: johnno56 on September 22, 2021, 02:43:37 am
Does anyone know how to simulate the min() and max() function using QB64?

To find the min and max values of an array?


FUNCTION min (array() AS LONG) ‘or other type as needed
    min = array(LBOUND(array))
    FOR i = LBOUND(array) TO UBOUND(array)
        if min > array(i) THEN min = array(i)
    NEXT
END FUNCTION

Same for max, basically.

The basic min() and max() command, that I am planning on,  will not be handling arrays but only two variables. From the example provided I should be able to work it out. Thanks Steve.

Steve just might be the sharpest tool in the shed... Oh wait, I can't believe I shed that!

You may want to revise that statement.  Remember Steve started this thread: https://www.qb64.org/forum/index.php?topic=4194.0

@johnno56  Can you show basic usage of the function you are planning?

This is min() and max() in p5js.bas (https://github.com/FellippeHeitor/p5js.bas/blob/master/p5js.bas):

Code: QB64: [Select]
  1. 'Calculate minimum value between two values
  2. Function min! (a!, b!)
  3.     If a! < b! Then min! = a! Else min! = b!
  5.  
  6. 'Calculate maximum value between two values
  7. Function max! (a!, b!)
  8.     If a! > b! Then max! = a! Else max! = b!

Remember, even the best of tools get wore out over time.  Have some pity on an old, broken down fat fellow — let ‘em have a few nice glories and kindly overlook all the countless failures.  😭😭😭

(And I still say that arrow is possessed by the devil and has hid from me for the last several years, just so I wouldn’t notice it and think the forums had broken!)

Why Steve,why?!

Oh well, when I throw out a compliment, I really throw out a compliment. Consider that one recycled!

Yep, sometimes even us sharpest tools shed all over ourselves.

Pete :D

SpriggsySpriggs,

I certain can. I am converting a simple Xmas-type game from Naalaa to QB64. At my skill level I should be done by Xmas! But it could be close... lol

Fillippe,

What is the purpose of the exclamation marks within a function? Just curious. (Thanks for the functions, by the way!)

... and how do you add those 'personal' blue hyper links to messages?

@johnno56   - In your "Profile" there are two input lines, one for the title of the site, and one for the link.

Exclamation points indicate data type SINGLE precision, for variables and functions.

To add a url to a post you use the [url] tag (or just click the globe button, next to the QB64 code box button in the post editor page. Try quoting my post to see the source.

Hmm, I thought Fell used his profile signature for that... Let's see if it works for me. Adding a message and link with   (http://) tags to my signature in my profile. Let's see if it worked...

@SMcNeill Everyone is allowed a DOH moment.  I lost count of my DOH's here.  That arrow is a bit small.  Hell I missed the big announcement in QB64 saying to exclude QB64 directory tree from virus scanning.  That was a real slap to the forehead event.
