I can see this coming in handy when splitting entries into multiple columns. I’ve always resorted to PHP parsed as input, but yet that even has it’s limitations and resorting to embed another include.

That’s exactly what I was trying to do but discovered division doesn’t work even though the plug-in code seems to look for / as well.

PixelGrinch,

Yeah it looks like it should work.  Tomorrow I’ll see if I can figure out what’s going on. Which version are you using? The experimental tag pair or the single solve tag version?

Hi Airways,

I used both versions the most recent single (1.0) and the most recent tag pair (2.2).

Thanks for the quick response ...

Well I haven’t been able to find a problem with division. The following test works:

{exp:will_hunting}
2 + 2 = {$n=2 + 2} {$n}

2 - 2 = {$n=2 - 2} {$n}

2 * 2 = {$n=2 * 2} {$n}

2 / 2 = {$n=2 / 2} {$n}

{/exp:will_hunting}

I would say double check your tying and if you do still have an issue, post a Bug Report with the offending code at the support forum for the plugin: http://devot-ee.com/add-ons/support/will-hunting/viewforum/1354/

Good luck!

Hi Airways,

trying the single tag currently installed:

this being the only code in the complete template:

12 * 3 = {exp:will_hunting solve="12 * 3"}

12 + 3 = {exp:will_hunting solve="12 + 3"}

rund(12.92 + 5) = {exp:will_hunting solve="round(12.92 + 5)"}

12 / 3 = {exp:will_hunting solve="12 / 3"}

returns:

12 * 3 = 36
12 + 3 = 15
rund(12.92 + 5) = 18
12 / 3 = 12

Maybe I am missing something. If you can’t reproduce this I will post a bug report as you mentioned in your prior post.

Okay well, I did finally recreate this in EE 1.7. Doesn’t occur in 2.0, so I am suspecting that it’s a weird parsing error in the Template class… might take awhile, but I will try to track it down.

Hi Airways,

I have clients that hire me to just find bugs 😊, for some reason I have a talent finding them! If there is a bug, I find it, HA!

Thanks for looking into this. Keep me updated on the status ... Have a great weekend!

Found it! Actually, I’ve seen this one before. EE 1.x has a habit of changing / into an HTML entity for some reason. This should have occurred to me before, it’s caused more than a few bugs in custom code we’ve written in the past. Anyway, fixed version now up at http://devot-ee.com/site/download/?file=will_hunting-2_3.zip

This version also brings back single template tags if you need them, with a slightly updated syntax:

{exp:will_hunting:solve exp="round(12.92 * 1234)" store="x"}
x = {exp:will_hunting:get var="x"}

Nice job mate! A++!

Hi Airways,

I was missing the Modulus (division remainder) operator. As a token of my appreciation for your quick replies and solution, I added ‘%’ support to Will Hunting. Feel free to check it out and integrate it into the next update of Will Hunting.
I have added a readme.txt file along with the file and it can be downloaded at:

pi.will_hunting_pg_231.zip

thanks again for your quick help yesterday, Airways!

Nice plugin - but how can you set the deminal places of the result?

I am using this to calculate the TAX on an item and need to set deminal place to 2 points

{exp:will_hunting solve="({cart_subtotal} + {cart_shipping} - {cart_discount}) * 0.16666666"}

Don’t worry - just modified the plugin file adding in this :

/**
     *  Evaluate an expression, returning the value
     */
    function evaluate($expr) {

        $this->expr = $expr;
        $this->tokenize();
        $this->pos = 0;
        $this->err = array();

        $value = number_format($this->eval_expr(),2); //this line was added to format the result as we are only using it for Tax purposes you might need to modify it more if you want to be able to select whether to use this output or not

        return $value;
    }

Good ideas, I’ll see about adding similar options to the next release.
